John M. Pierce (1886 – March 4, 1958) was an American teacher and amateur astronomer.
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies.
Pierce worked with Russell W. Porter to organize Stellafane, the observatory near Springfield, Vermont where amateur telescope makers still meet annually for the Stellafane convention. He was one of the earliest members of the Springfield Telescope Makers and served as its vice president.
Russell Williams Porter was an American artist, engineer, amateur astronomer and Arctic explorer. He was a pioneer in the field of “cutaway illustration" and is sometimes referred to as the "founder" or one of the "founders" of amateur telescope making."
Stellafane is the name of the clubhouse built by the Springfield Telescope Makers club of Springfield, Vermont in the early 1920s, and has since come to refer to the club's land and buildings on the summit of Breezy Hill. It also refers to the Stellafane Convention, a gathering of amateur telescope makers and amateur astronomers held every year at that location. The property is a National Historic Landmark.
Springfield is a town in Windsor County, Vermont, United States. The population was 9,373 at the 2010 census.
Pierce contributed many articles to the telescope making column conducted by Albert G. Ingalls in Scientific American , and wrote several chapters in the Amateur Telescope Making series of books, including "Motor Drives", "Making Astronomical Flats", and "A Telescope Anyone Can Make" (the latter appeared only in the earliest printings). When the hobby was new and supplies were hard to come by, Pierce set up a small business to provide kits and parts for amateur astronomers. [1]
Scientific American is an American popular science magazine. Many famous scientists, including Albert Einstein, have contributed articles to it. It is the oldest continuously published monthly magazine in the United States.
Amateur Telescope Making (ATM) is a series of three books edited by Albert G. Ingalls between 1926 and 1953 while he was an associate editor at Scientific American. The books cover various aspects of telescope construction and observational technique, sometimes at quite an advanced level, but always in a way that is accessible to the intelligent amateur. The caliber of the contributions is uniformly high and the books have remained in constant use by both amateurs and professionals.
In 1933 and 1934 he published a series of 14 articles on telescope making in Hugo Gernsback's Everyday Science and Mechanics called "Hobbygrafs" (or sometimes "Hobbygraphs").
Hugo Gernsback was a Luxembourgish-American inventor, writer, editor, and magazine publisher, best known for publications including the first science fiction magazine. His contributions to the genre as publisher–although not as a writer–were so significant that, along with the novelists H. G. Wells and Jules Verne, he is sometimes called "The Father of Science Fiction". In his honour, annual awards presented at the World Science Fiction Convention are named the "Hugos".
Robert E. Cox, in an obituary for Sky and Telescope magazine in 1958, considered John M. Pierce on a par with Ingalls and Porter, describing him as one of "the big three behind the amateur telescope making movement in America." [2]
Robert Edward Cox was an American optical engineer and a popularizer of amateur telescope making. He conducted the popular "Gleanings for ATMs" column in Sky and Telescope magazine for 21 years.
Pierce graduated in architectural engineering from Pratt Institute in 1910. He spent most of his life as a teacher; from 1919 to 1956 he was director of the Springfield High School co-operative course, which included training in machine-tool work, cabinet making, sheet-metal work and auto repair. He was also active in civic affairs and well known as a musician and amateur geologist. [1]
Pratt Institute is a private, nonsectarian, non-profit institution of higher learning located in the Clinton Hill neighborhood of Brooklyn, New York, United States, with a satellite campus located at 14th Street in Manhattan and an extension campus in Utica, New York. The school originated in 1887 with programs primarily in engineering, architecture, and fine arts. Comprising six schools, the Institute is primarily known for its highly ranked programs in architecture, interior design, and industrial design, and offers both undergraduate and Master's degree programs in a variety of fields, with a strong focus on research.
Springfield High School (SHS) is a public high school in the town of Springfield in southern Vermont, United States. It is part of the Springfield School District and serves students from Springfield and neighboring Weathersfield. SHS is accredited by the New England Association of Schools and Colleges.
Amateur telescope making is the activity of building telescopes as a hobby, as opposed to being a paid professional. Amateur telescope makers build their instruments for personal enjoyment of a technical challenge, as a way to obtain an inexpensive or personally customized telescope, or as a research tool in the field of astronomy. Amateur telescope makers are usually a sub-group in the field of amateur astronomy.
A Dobsonian telescope is an altazimuth-mounted Newtonian telescope design popularized by John Dobson in 1965 and credited with vastly increasing the size of telescopes available to amateur astronomers. Dobson's telescopes featured a simplified mechanical design that was easy to manufacture from readily available components to create a large, portable, low-cost telescope. The design is optimized for observing faint, deep-sky objects such as nebulae and galaxies. This type of observation requires a large objective diameter of relatively short focal length and portability for travel to relatively less light-polluted locations.
The Amateur Scientist was a column in the Scientific American, and was the definitive "how-to" resource for citizen-scientists for over 72 years (1928–2001), making it the longest running column in Scientific American's history. The column was regarded for revealing the brass-tacks secrets of research and showing home-based experimenters how to make original discoveries using only inexpensive materials. Since its début in 1928, "The Amateur Scientist" was a primary resource for science fair projects. It also inspired amateur experimenters, launched careers in science, and enjoyed a place of honor in classrooms and school libraries all over the world.
Since its founding in 1911, the American Association of Variable Star Observers (AAVSO) has coordinated, collected, evaluated, analyzed, published, and archived variable star observations made largely by amateur astronomers and makes the records available to professional astronomers, researchers, and educators. These records establish light curves depicting the variation in brightness of a star over time.
Albert Graham Ingalls was an American scientific editor and amateur astronomer. Through his columns in Scientific American, including "The Amateur Scientist", and his three-volume series Amateur Telescope Making, Ingalls exerted a great influence on amateur astronomy and amateur telescope making in the United States.
James Gilbert Baker was an American astronomer and designer of optics systems.
Astronomy is a monthly American magazine about astronomy. Targeting amateur astronomers for its readers, it contains columns on sky viewing, reader-submitted astrophotographs, and articles on astronomy and astrophysics that are readable by nonscientists.
James Hartness was an American inventor; a mechanical engineer; an entrepreneur who mentored other inventors to develop their machine tool products and create a thriving industrial center in southeastern Vermont; an amateur astronomer who fostered the construction of telescopes by amateurs in his town; an early aviator who built one of Vermont's first airports; and the 58th Governor of Vermont from 1921 to 1923.
Reverend William Frederick Archdall Ellison FRAS was an Irish clergyman, Hebrew scholar, organist, avid amateur telescope maker, and, from 1918 to 1936, director of Armagh Observatory in Armagh, Northern Ireland. He was the father of Mervyn A. Ellison, the senior professor of the School of Cosmic Physics at Dunsink Observatory from 1958 to 1963.
PLate OPtimizer, or PLOP is a CAD program used by amateur telescope makers to design primary mirror support cells for reflecting telescopes. It was developed by telescope maker David Lewis, first described in 1999, and used to simplify calculations needed in the design of mirror support cells. It was based on Toshimi Taki's 1993 program PLATE, with a simplified user interface, thus giving it wide acceptance among makers of large Dobsonian style amateur telescopes, with good support of mirrors as thin as two inches for a diameter of thirty inches.
In astronomy, a mirror support cell - more commonly mirror cell - is a component of a reflecting telescope that supports the mirror in place to hold optical alignment, allow collimation adjustment, and protect it from falling out. The common usage of the word denotes the cell that holds the primary mirror (M1), however technically it could also be used to denote the support assembly for the secondary mirror (M2) or other mirrors.
John F. Gregory was an American optical engineer and a popularizer of amateur telescope making. He is credited with the design of a version of the Maksutov telescope called the "Gregory-Maksutov telescope".
The Porter Garden Telescope, was an innovative ornamental telescope for the garden designed by Russell W. Porter and commercialized by Jones & Lamson Machine Company at the beginning of the 1920´s in the United States.
