	CSHL - History: Alfred Hershey
		Al Hershey was working on a little-studied organism called bacteriophage with phage researcher J.J. Bronfenbrenner at Washington University in St. Louis when he received a letter from the brash and brilliant German scientist at Vanderbilt University, Max Delbruck.
		Hershey went, and thus formed the third point in the nucleus of the nascent American phage group.
		Hershey allowed this to occur, but then at the crucial moment he whirred them in a Waring Blendor, which he had discovered produced just the right shearing force to tear the phage particles from the bacterial walls but not rupturing the bacteria.

	Alfred Hershey - MSN Encarta
		Alfred Hershey (1908-1997), American geneticist and winner of the 1969 Nobel Prize in physiology or medicine, which he shared with Italian-born American microbiologist Salvador Edward Luria and German-born American biologist Max Ludwig Henning Delbrück for their discoveries concerning the replication mechanism of viruses and their genetic structure.
		Six years later, in 1952, Hershey and American geneticist Martha Chase conducted their famous “blender experiment” in which, using a Waring blender, they separated the protein coating of the bacteriophage from its nucleic acid core.
		Hershey's work contributed directly to this discovery, and also to the development of vaccines against polio, measles, and mumps.

	Alfred Hershey Summary
		The task before Hershey was to show that it was the phage DNA that was passed on to succeeding generations and that gave the signal for replication and growth.
		Hershey was "known to his colleagues as a very quiet, withdrawn sort of man who avoids crowds and noise and most hectic social activities," according to the report of the 1969 Nobel Prize in the October 17, 1969, New York Times.

	Hershey, Alfred Day (1908-1997): World of Microbiology and Immunology
		By seeking to understand the reproduction of viruses, Alfred Day Hershey made important discoveries about the nature of deoxyribonucleic acid (DNA) and laid the groundwork for modern molecular genetics.
		Highly regarded as an experimental scientist, Hershey is perhaps best known for the 1952 "blender experiment" that he and Martha Chase conducted to demonstrate that DNA, not protein, was the genetic material of life.
		Hershey's work with bacteriophages, the viruses that prey on bacteria, was often carried out in loose collaboration with other scientists working with bacteriophages.

	Martha Chase Summary
		Hershey was honored as one of the founders of molecular biology, and shared the 1969 Nobel Prize in medicine or physiology with Salvador Luria and Max Delbrück.
		Hershey and Chase found that most of the bacteriophage DNA remained with the bacterial cells while their protein coats were released into the medium.
		By marking bacteriophages with radioactive isotopes, Hershey and Chase were able to trace protein and DNA to determine which is the molecule of heredity.

		Hershey was offered a position at Indiana University in 1950, but took a job at the Genetics Research Unit, Carnegie Institution of Washington at Cold Spring Harbor on Long Island, New York, because he preferred to work in a laboratory environment.
		Hershey’s experiment led to the expressions (among research scientists) “Hershey heaven,” which is an experiment that can be repeated day after day with the same positive results and “Hershey’s circles,” which are a series of experiments that lead back to the beginning.
		Hershey and Chase determined that the protein shell is a transporting mechanism for DNA, protecting it, attaching it to the host, and injecting it into the host.

	Alfred Day Hershey
		Delbruck incorrectly interpreted his results as specifically induced mutations, but Hershey and one of his students proved that the results they had obtained were recombinations by showing that the genetic processes in question correspond with the crossing-over of parts of similar chromosomes observed in cells of higher organisms.
		Hershey is most noted for the so-called blender experiment that he performed with Martha Chase in 1952.
		By showing that phage DNA is the principal component entering the host cell during infection, Hershey proved that DNA, rather than protein, is the genetic material of the phage.

		Alfred Hershey was born on December 4, 1908, in Owosso, Mich (about 30 miles northeast of Lansing).
		Hershey’s early research was on the chemistry of Brucella bacteria and in the area of immunology.
		In 1952, Hershey and colleagues showed that during viral infection, the viral nucleic acid (and not the protein associated with it) enters the cell—that is, the genetic material is the nucleic acid, not the protein.

		The centerpiece was Hershey's evidence which confirmed through the Hershey-Chase blender experiments that DNA was the genetic material of inheritance.
		Hershey focused on two phage systems: T-even phages (tadpole-like structures, as referred to by Hershey) for DNA inheritance and recombination, and phage lambda, which provided a mechanism for understanding cell-to-cell transfer and a mechanism for introducing (through specialized transduction) cellular genes into Escherichia coli.
		Alfred Hershey and the Phage Group spawned multiple generations of phage users and lovers who opened the door to modern molecular biology.

		Max Delbrück (1906-1981), Alfred D. Hershey (1908-1997), and Salvador E. Luria (1912-1991) received the Nobel Prize in Physiology or Medicine for founding the phage group and stimulating hundreds of scientists to study molecular biology.

		Therefore, Delbrück, Hershey and Luria must in fact be regarded as the original founders of the modern science of molecular biology.
