Robert William Schmieder (born July 10, 1941) is an American scientist and explorer. Schmieder has had a multidisciplinary career, broadly divided between physics and related physical sciences, and natural science and exploration. In most of his projects, he created and led teams of both professional scientists and volunteers. His work is documented in about 100 technical publications and 10 books. Among his most significant work was the invention of laser spark spectroscopy (now commercialized), the formulation of nanologic (the use of nanoscale devices in computers), and the concept of underwater islands (which led to designation of the Cordell Bank National Marine Sanctuary).
Schmieder was born and grew up in Phoenix, Arizona, a member of a large family who were descendants of pioneers. His maternal grandmother migrated on horseback from Texas to the mining town of Superior, in the Arizona Territory. His father emigrated from Germany as a watchmaker and was later a businessman. As a child, Robert demonstrated an exceptional curiosity and interest in science, and decided on his career before the age of 12. In high school, he won several science awards, including the Westinghouse Science Talent Search and the Arizona State Science Fair. He was among the first in the United States to develop amateur rocketry, stimulated by events that led to the first Earth satellites in 1957.

Schmieder's research career in physical science began while an undergraduate at Caltech, when he wrote his first technical papers. [1] [2] [3] [4] [5] While still an undergraduate, he worked at the CIT synchrotron laboratory, and he participated in the discovery of a new isotope (In106) using the Berkeley 60-inch cyclotron. [6] For his PhD thesis at Columbia University, under the direction of Allen Lurio and William Happer, he made a definitive series of measurements of the hyperfine structure constants and lifetimes of the free alkali atoms. [7] [8] [9] As a post-doc at the Lawrence Berkeley National Laboratory, under the guidance of Richard Marrus, he was the first to produce highly stripped atoms in a high-energy accelerator (the Berkeley HILAC) and to observe relativistic and multipole atomic transitions in those ions. [10] [11] [12] [13] [14] [15] [16] This work led to the new field of "high-energy atomic physics." He also made significant contributions to instrumentation for X-ray spectroscopy, including the Doppler-tuned XRay spectrometer, [17] [18] [19] the electron ring accelerator as a spectroscopic source, [20] [21] [22] laser modulation of electron beams, [23] superconducting switches, [24] [25] and laser/microwave gas breakdown. [26] [27]
In the early 1970s, he accepted a position at Sandia National Laboratories, Livermore. His first work at Sandia was the 1976 invention of laser spark spectroscopy, [28] [29] [30] [31] [32] [33] [34] [35] [36] a technique that is now commercialized [see Supplemental references]. During the early 1980s, he was the first to record the UV fluorescence spectrum of acetylene, [37] the emission spectrum of pure tritium gas, [38] the use of tritium for radiolytic polymerization of hydrocarbons, [39] [40] and the use of carbon-14 to track reaction pathways in carbon formation in flames. [41]
During the Strategic Defense Initiative period (mid-1980s), he led the effort to calculate the effects of clustering of X-ray lasers. [42] Following the SDI, he led a team that built two state-of-the-art electron beam ion sources (EBIS), obtaining highly charged ions up to Xe+46 in laboratory experiments and a design capability of U+90. [43] [44] [45] [46] [47] [48] [49] [50] [51] [52] [53] During the early 1990s, he was Principal Investigator of a team that developed an advanced model and simulation code for the plasma color video display, part of a national initiative that produced the current flat-panel display. [54] [55] He also developed a new model of collective dynamics of minimally cognitive populations, and applied it to various dynamical systems, including biological populations and artificial life. [56] [57] [58] [59]
During the mid-1990s, Schmieder's interest turned to nanotechnology. In a collaboration with Robert Bastasz, he was the first to observe Coulomb explosion on a solid surface, [60] from which they developed a new process using high charge state ions for fabricating nanoelectronic devices, [61] [62] and recognized the potential of such systems to high-density computing and information technology. [63] [64] Schmieder's key insight following that work was that nanoscale devices are intrinsically hybrid analog/digital, and therefore the optimum architecture and data structures for data processing arrays also should be hybrid A/D. He named this new technology "nanologic." In 1997, he left Sandia to found a startup company NanoLogic, Inc., but after an initial round of funding, the market collapse of 2000 made it impossible to obtain further funding and the company became inactive. [65]
Schmieder continues research into nanologic as a new paradigm for machine-assisted problem solving. In particular, he develops the rigorous mathematical basis of applications of nanologic, and performs experiments with systems to demonstrate the principles of the technology. He emphasizes that a nanologic machine is not a computer in the sense of performing computations, but a machine for abstracting the meaning from incomplete or imperfect information and making "intelligent" conclusions or predictions. In this sense, nanologic is closer to human cognition and analysis than to computation.
During his years at Berkeley, he worked with Albert Ghiorso, the discoverer of 12 transuranic chemical elements. He is currently (2013) writing a scientific biography: Element: The Amazing Life and Work of Albert Ghiorso.
Dr. Schmieder's work in natural science and exploration began in the mid-1970s, when he began to organize and lead a series of scientific expeditions to extremely remote oceanic locations. To formalize the work, he established a nonprofit organization, Cordell Expeditions. Throughout these projects, he coordinated the work of a large number of specialists and volunteers, ensuring the scientific viability of extensive collections of specimens and observational data. The work led to many discoveries in geography, geology and marine biology, including numerous new species named to honor the expeditions and personnel (Armina cordellensis, Codium schmiederi, Erylus schmiederi, Halcelia bozanici, Homalopoma cordellensis, Megalomphalus schmiederi, Ophioderma vansyoci, Paratimea alijosensis, Pharia pyramidata schmiederi, Thor cordelli). Cumulatively, Cordell Expeditions is responsible for the field work leading more than 1000 new species, new genera, first recorded observations, and range/depth extensions. [66]
Schmieder's first, and most extensive, field project was the exploration of Cordell Bank, a rocky bank west of Pt. Reyes, California. Over nearly 10 years (1977–86), he and his group explored and described the bank. [67] [68] [69] [70] [71] [72] [73] [74] [75] [76] [77] [78] [79] [80] [81] [82] [83] [84] [85] As a result of this work, the Cordell Bank National Marine Sanctuary was designated in 1989 by an Act of Congress, signed by Pres. George H. W. Bush. [86] [87] draft environmental impact statement and management plan for the proposed Cordell Bank National Marine Sanctuary, Marine and Estuarine Management Division, Office of Coastal Resource Management, National Ocean Service, NOAA, May, 1987. [88] [89] [90] [91] [92] [93] [94] [95] [96] [97] In the course of this project, Schmieder published papers on the geological structure of the bank, [98] morphology and speciation of a resident gastropod, [99] [100] local history, [101] and the impact of human activities on the biological community. [102] [103] [104] [105] [106] [107] culminating with the definitive case study Ecology of an Underwater Island. [108] A second monograph, Edward Cordell and the Discovery of Cordell Bank, is completed but not yet published. [109] The Oakland (CA) Museum has a permanent exhibit on Cordell Bank, displaying and honoring the work of Cordell Expeditions.
During 1986–87, Schmieder's team carried out a series of explorations of an unnamed bank off Pt. Sur, south of Monterey, California, resulting in the discovery of previously unknown topographic features and the largest known colonies of the California hydrocoral. [110] This work resulted in the inclusion of sensitive areas within the proposed Monterey Bay National Marine Sanctuary. Following a recommendation by Dr. Sylvia Earle (National Oceanic and Atmospheric Administration), Dr. Paul Silva (UC Berkeley), and Dr. Melanie Stright (U.S. Minerals Management Service), it was named Schmieder Bank by the U. S. Board of Geographic Names. [111] [112] [113]
North Farallon Island: In the late 1980s, his team explored the North Farallon Islands, resulting in the discovery of many new biological records and a previously unknown (natural) submarine tunnel. [114]
Rocas Alijos: In 1990 and again in 1993, Schmieder and a team of thirty carried out the first comprehensive scientific expeditions to Rocas Alijos, Baja California. The monograph Rocas Alijos, published in 1994 by Kluwer Academic Publishers, resulted from these expeditions. [115]
Guadalupe Island: This was a radio expedition done in 1993 in conjunction with the Rocas Alijos project.
Roqueta Island: A radio expedition done in 1994. [116]
Peter I Island: In 1994 he participated in an expedition to Peter I Island, Antarctica, documented in his book 3YØPI. [117]
Easter Island: In 1995 he carried out a complex and ambitious expedition to Easter Island, during which the team examined the unexplored marine areas. This expedition was the first on record to have a real-time interactive website and e-mail direct to the remote site. It is documented in his book DX-Aku: Messages from the Easter Island Expedition. [118]
Heard Island: In 1997 he organized and led the extraordinary expedition to Heard Island, Antarctica, during which his team logged a world-record number of radio contacts (more than 80,000). His book, VKØIR: The Heard Island Expedition, describes the expedition. [119]
San Felix Island: In 2002 he was an organizing member of the expedition to San Felix Island, Chile, the first non-military group to visit the island. This expedition is documented in his book XRØX The 2002 Expedition to San Felix. [120]
Kure Atoll: In 2005 he was the Principal Organizer and Expedition Leader of the expedition to Kure Atoll, NW Hawaiian Islands. For this project, he developed an internet application (DXA), the first website for displaying data from the remote site in real time on a web browser. The website received more than 40 million hits during the expedition. [121]
Clipperton Island: Schmieder organized and led the March, 2013, expedition to Clipperton Island. The team of 29 made the first discovery of foraminifera on Clipperton and set a record for the number of radio contacts from there (113,601). This expedition and the 2005 expedition to Kure (above) are described in his book DXA. The Real-time Online Radio Log Server. [122]
Heard Island: In 2016, Schmieder carried out a second major research expedition to Heard Island. [123] The team made extensive observations of the volcano Big Ben, environmental changes due to climate change, and real-time communications using amateur radio. In 2023 he completed his book Heard Island: Two Centuries of Change, and More Coming. It is published by Springer, 900+ pages, 2023.
Pitcairn Island: In 2018 Schmieder and a colleague carried out an expedition to Pitcairn Island, for the purpose of studying foraminifera, microscopic single-celled organisms of importance in dating fossil sediments.
St. Paul Island: In 2019 Schmieder and a colleague carried out an expedition to St. Paul Island (Pribilofs), for the purpose of studying foraminifera.
Azores Islands: In 2022 Schmieder, his younger son, and two colleagues carried out two expeditions to the Azores, for the purpose of studying the recolonization of ocean floor that had been destroyed by lava flow from the 1956 eruption of the volcano at Caplinhos on Faial Island.
In 1986, Schmieder acquired and outfitted a research vessel, the Cordell Explorer, and used it in some of the research expeditions. In recent years, he has used the vessel principally for educational programs, taking more than 300 students each year on 1-day cruises to learn about the marine environment and techniques for monitoring and research. [124]
Dr. Schmieder was born July 10, 1941, in Phoenix, Arizona. His father (Otto Schmieder) emigrated from Germany in the 1920s, and became a very successful businessman. [125] His mother (Ruby Harkey) was part of a pioneer family in the territory of Arizona. [126]
His brother (Carl Schmieder) was a distinguished businessman and aviator [127] before losing his life at age 60 in a private aircraft accident. He has three grown children (Robyn (Schmieder) Thelin, Russell Schmieder, and Randy Schmieder), and six grandchildren. He is married to Kathleen (Deal) Schmieder, a school teacher for 28 years and currently a businesswoman.

In 2011, he was inducted into the Amateur Radio Hall of Fame.
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion. Ionization can result from the loss of an electron after collisions with subatomic particles, collisions with other atoms, molecules, electrons, positrons, protons, antiprotons and ions, or through the interaction with electromagnetic radiation. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected.
An ion laser is a gas laser that uses an ionized gas as its lasing medium. Like other gas lasers, ion lasers feature a sealed cavity containing the laser medium and mirrors forming a Fabry–Pérot resonator. Unlike helium–neon lasers, the energy level transitions that contribute to laser action come from ions. Because of the large amount of energy required to excite the ionic transitions used in ion lasers, the required current is much greater, and as a result almost all except for the smallest ion lasers are water-cooled. A small air-cooled ion laser might produce, for example, 130 milliwatts of output light with a tube current of about 10 amperes and a voltage of 105 volts. Since one ampere times one volt is one watt, this is an electrical power input of about one kilowatt. Subtracting the (desirable) light output of 130 mW from power input, this leaves the large amount of waste heat of nearly one kW. This has to be dissipated by the cooling system. In other words, the power efficiency is very low.
Cordell Bank National Marine Sanctuary is a marine sanctuary located off the coast of California. It protects an area of 1,286 sq mi (3,331 km2) of marine wildlife. The administrative center of the sanctuary is on an offshore granite outcrop 4.5 sq mi (12 km2) by 9.5 sq mi (25 km2), located on the continental shelf off of California. The outcrop is, at its closest, 6 mi (10 km) from the sanctuary itself.
Thorium (90Th) has seven naturally occurring isotopes but none are stable. One isotope, 232Th, is relatively stable, with a half-life of 1.405×1010 years, considerably longer than the age of the Earth, and even slightly longer than the generally accepted age of the universe. This isotope makes up nearly all natural thorium, so thorium was considered to be mononuclidic. However, in 2013, IUPAC reclassified thorium as binuclidic, due to large amounts of 230Th in deep seawater. Thorium has a characteristic terrestrial isotopic composition and thus a standard atomic weight can be given.
Rocas Alijos, or Escollos Alijos are a series of tiny, steep, uninhabited, and barren volcanic islets or above-water rocks in the Pacific Ocean at 24°57′31″N115°44′59″W. They are part of Comondú municipality of the Mexican state of Baja California Sur, and situated about 300 kilometres (190 mi) west of the mainland. The total surface area is 0.012 square kilometres (0.0046 sq mi).
Schmieder Bank is a rocky undersea bank west of Point Sur, California, roughly 25 nautical miles (46 km) south of Monterey, supporting an extraordinarily lush biological community, including very large individual colonies of the California hydrocoral, Stylaster californicus.
Penning ionization is a form of chemi-ionization, an ionization process involving reactions between neutral atoms or molecules. The Penning effect is put to practical use in applications such as gas-discharge neon lamps and fluorescent lamps, where the lamp is filled with a Penning mixture to improve the electrical characteristics of the lamps.
This page deals with the electron affinity as a property of isolated atoms or molecules. Solid state electron affinities are not listed here.
Photofragment ion imaging or, more generally, Product Imaging is an experimental technique for making measurements of the velocity of product molecules or particles following a chemical reaction or the photodissociation of a parent molecule. The method uses a two-dimensional detector, usually a microchannel plate, to record the arrival positions of state-selected ions created by resonantly enhanced multi-photon ionization (REMPI). The first experiment using photofragment ion imaging was performed by David W Chandler and Paul L Houston in 1987 on the phototodissociation dynamics of methyl iodide (iodomethane, CH3I).
Laser-based angle-resolved photoemission spectroscopy is a form of angle-resolved photoemission spectroscopy that uses a laser as the light source. Photoemission spectroscopy is a powerful and sensitive experimental technique to study surface physics. It is based on the photoelectric effect originally observed by Heinrich Hertz in 1887 and later explained by Albert Einstein in 1905 that when a material is shone by light, the electrons can absorb photons and escape from the material with the kinetic energy: , where is the incident photon energy, the work function of the material. Since the kinetic energy of ejected electrons are highly associated with the internal electronic structure, by analyzing the photoelectron spectroscopy one can realize the fundamental physical and chemical properties of the material, such as the type and arrangement of local bonding, electronic structure and chemical composition.
Anthony E. Siegman was an electrical engineer and educator at Stanford University who investigated and taught about masers and lasers. Known to almost all as Tony Siegman, he was president of the Optical Society of America [now Optica (society)] in 1999 and was awarded the Esther Hoffman Beller Medal in 2009.
David Jeffery Wineland(born February 24, 1944) is an American Nobel-laureate physicist at the National Institute of Standards and Technology (NIST). His work has included advances in optics, specifically laser-cooling trapped ions and using ions for quantum-computing operations. He was awarded the 2012 Nobel Prize in Physics, jointly with Serge Haroche, for "ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems".
Electron nuclear double resonance (ENDOR) is a magnetic resonance technique for elucidating the molecular and electronic structure of paramagnetic species. The technique was first introduced to resolve interactions in electron paramagnetic resonance (EPR) spectra. It is currently practiced in a variety of modalities, mainly in the areas of biophysics and heterogeneous catalysis.
Victor Ivanovich Balykin is a Russian physicist whose main contributions are in the field of atom optics. He and his associates first demonstrated laser cooling of neutral atoms in 1981.
Renato Zenobi is a Swiss chemist. He is Professor of Chemistry at ETH Zurich. Throughout his career, Zenobi has contributed to the field of analytical chemistry.
Magnetized liner inertial fusion (MagLIF) is an ongoing fusion power experiment being carried out on the Z Pulsed Power Facility at Sandia National Laboratories in the US. Is it one example of the broader magneto-inertial fusion approach, which attempts to compress a pre-heated plasma. The goal is to produce fusion conditions without the level of compression needed in the inertial confinement fusion (ICF) approach, where the required densities reach about 100 times that of lead.
Modern spectroscopy in the Western world started in the 17th century. New designs in optics, specifically prisms, enabled systematic observations of the solar spectrum. Isaac Newton first applied the word spectrum to describe the rainbow of colors that combine to form white light. During the early 1800s, Joseph von Fraunhofer conducted experiments with dispersive spectrometers that enabled spectroscopy to become a more precise and quantitative scientific technique. Since then, spectroscopy has played and continues to play a significant role in chemistry, physics and astronomy. Fraunhofer observed and measured dark lines in the Sun's spectrum, which now bear his name although several of them were observed earlier by Wollaston.
Xenon monochloride (XeCl) is an exciplex which is used in excimer lasers and excimer lamps emitting near ultraviolet light at 308 nm. It is most commonly used in medicine. Xenon monochloride was first synthesized in the 1960s. Its kinetic scheme is very complex and its state changes occur on a nanosecond timescale. In the gaseous state, at least two kinds of xenon monochloride are known: XeCl and Xe
2Cl, whereas complex aggregates form in the solid state in noble gas matrices. The excited state of xenon resembles halogens and it reacts with them to form excited molecular compounds.
Walter Thompson Welford was a British physicist with expertise in optics.
