Early life and education

Harold Blum was born on February 12, 1899, in Escondido, California. For a year during the First World War, he served with the American Expeditionary Forces Signal Corps in France. Blum graduated in 1922 from the University of California, Berkeley, with an A.B. in zoology with honors. He attended Harvard Medical School from 1923 to 1924, then returned to Berkeley for a Ph.D. in physiology and graduated in 1927. During his PhD studies Blum worked for the San Francisco Bay Marine Piling Committee. Blum completed postdoctoral studies at the Laboratoire Maritime de Concarneau in France and the University of Liège in Belgium in 1933. [1] [2]

Career

Harold Blum was an assistant professor of animal biology at the University of Oregon, then an instructor of physiology at Harvard Medical School. He became an assistant professor, then associate professor, of physiology at the University of California at Berkeley. In 1938, Blum was a founding member of the National Cancer Institute. Blum's 1940 book Photodynamic Action and Diseases Due to Light, written during the first of his three Guggenheim Fellowships (awarded in 1936, 1945, and 1953), was a classic text used in medical schools for many years. The book earned the Medal of the University of Liège. From 1943-1946 during the Second World War, he was a principal biophysicist of the Naval Medical Research Institute. In 1947 Blum became visiting professor at Princeton University, where he spent 20 years. [1]

In 1951 Blum published Time's Arrow and Evolution, [3] which "explores the relationship between time's arrow (the second law of thermodynamics) and organic evolution." This influential text studies "irreversibility and direction in evolution and order, negentropy, and evolution." [4] Blum argues that evolution followed specific patterns predetermined by the inorganic nature of the earth and its thermodynamic processes. [5] Scholar Robert Scholes, writing about influences on science fiction, calls the work a "milestone in science writing" that is "one of the finest pieces of science writing ever done." [6]

Blum retired from Princeton University and the US Public Health Service in 1967. After retirement, he was a professor, then professor emeritus, of biology at State University of New York at Albany. From 1973 until his death in 1980, Harold Blum was visiting professor of photobiology at the Center for Photobiology, Skin and Cancer Hospital of the Temple University School of Medicine. [1]

Harold Blum died in Philadelphia, Pennsylvania, on September 29, 1980. [1]

The arrow of time, also called time's arrow, is the concept positing the "one-way direction" or "asymmetry" of time. It was developed in 1927 by the British astrophysicist Arthur Eddington, and is an unsolved general physics question. This direction, according to Eddington, could be determined by studying the organization of atoms, molecules, and bodies, and might be drawn upon a four-dimensional relativistic map of the world.

Albert Claude was a Belgian-American cell biologist and medical doctor who shared the Nobel Prize in Physiology or Medicine in 1974 with Christian de Duve and George Emil Palade. His elementary education started in a comprehensive primary school at Longlier, his birthplace. He served in the British Intelligence Service during the First World War, and got imprisoned in concentration camps twice. In recognition of his service, he was granted enrolment at the University of Liège in Belgium to study medicine without any formal education required for the course. He earned his Doctor of Medicine degree in 1928. Devoted to medical research, he initially joined German institutes in Berlin. In 1929 he found an opportunity to join the Rockefeller Institute in New York. At Rockefeller University he made his most groundbreaking achievements in cell biology. In 1930 he developed the technique of cell fractionation, by which he discovered the agent of the Rous sarcoma, components of cell organelles such as mitochondrion, chloroplast, endoplasmic reticulum, Golgi apparatus, ribosome and lysosome. He was the first to employ the electron microscope in the field of biology. In 1945 he published the first detailed structure of cell. His collective works established the complex functional and structural properties of cells.

<span class="mw-page-title-main">Ruth Sager</span> American geneticist

Ruth Sager was an American geneticist. Sager enjoyed two scientific careers. Her first was in the 1950s and 1960s when she pioneered the field of cytoplasmic genetics by discovering transmission of genetic traits through chloroplast DNA, the first known example of genetics not involving the cell nucleus. The academic community did not acknowledge the significance of her contribution until after the second wave of feminism in the 1970s. Her second career began in the early 1970s and was in cancer genetics; she proposed and investigated the roles of tumor suppressor genes.

David Burton Wake was an American herpetologist. He was professor of integrative biology and Director and curator of herpetology of the Museum of Vertebrate Zoology at the University of California, Berkeley.

He has served as president of the Society for the Study of Evolution, the American Society of Naturalists, and American Society of Zoologists. He was a member of the American Association for the Advancement of Science, the Linnean Society of London, the American Academy of Arts and Sciences, the American Philosophical Society, and in 1998 was elected into the National Academy of Sciences. He was awarded the 2006 Leidy Award from the Academy of Natural Sciences of Philadelphia.

Robert Elliot Pollack is an American biologist whose interests cross many academic lines. He grew up in Brooklyn, attended public schools, and majored in physics at Columbia University, where he graduated from the College in 1961. He received a PhD in Biological Sciences from Brandeis University in 1966, and subsequently was a postdoctoral Fellow in Pathology with Howard Green at NYU Medical center, and at the Weizmann Institute in Israel with Ernest Winocour. He was then recruited to Cold Spring Harbor Laboratory by James Watson to establish a research program on reversion of cancer cells. He became a tenured Associate Professor of Microbiology at the Stony Brook University Medical Center before returning to Columbia as a Professor of Biological Sciences in 1978. He served as Dean of Columbia College from 1982 to 1989, overseeing the enrollment of women in the College for the first time.
