Erwin Chargraff is born
Erwin Chargraff is born in Austria-Hungary. Later in life, Chargraff became a biochemist at Columbia University. He discovered two rules, "Chargraff's Rules" that helped lead to the discovery of the double helix in DNA. The rules saying that for every guanine, there should be an equal amount of cytosine. This also applies to adenine and thymine. -
Colin Munro MacLeod is born
MacLeod is born in Novia Scotia, Canada. He is known for taking part in the "Avery- MacLeod- McCarty Experiment". This experiment proved that DNA was the heriditary material that was transfered from parents to offspring. -
Maclyn McCarty is born
McCarty is born in South Bend, Indiana. He is famous for taking part in the "Avery-MacLeod-McCarty Experiment". In the experiment, they discovered that DNA is the carrier of genes. He died in 2005 at the age of 93 and he contributed a lot to the science world. -
Francis Crick is born
Francis Cook is born in England on June 8, 1916. He grew up in the United Kingdom and became a molecular biologist. He is most famous for his co-discovery of the structure of DNA with his partner, James Watson. He was awarded for his disovery with the Nobel Prize. -
James Watson is born
James Watson is born in Chicago, Illinois. He is most famous for the co-discovery of the structure of DNA in 1953 with Francis Crick. He has also written a book and attended excellent univeristies such as Harvard and Cambridge. -

Daniel Nathans is born in Wilmington, Delaware and became a microbiologist. He is most famous for sharing the Nobel Prize for his discovery. His discovery was restriction enzymes. He along with two other men were able to make this discovery. -
Werner Arber is born
Werner Arber is born in Switzerland. He is a micobiologist most famous for the discovery of restriction endonucleuses, or the abiliy of enzymes to cut DNA. He discovered this with the help of two other scientists, Smith and Nathans. -
Hamilton Smith is born
Smith is a Nobel Prize winner for his discoveries in microbiology. He, along with two others, was able to discover bacterial restriction enzymes that cut DNA. He attended University of California Berkeley and Jonns Hopkins School of Medicine. -
Herbert Boyer is born
Herbert Boyer, an American Biology Scientist, is born in Derry, Pennsylvania. He is most known for researching and entrepreuning in Biotechnology. With the help of others, he discovered a method to coax bacteria into producing foreign proteins. -
John C. Sanford
John C. Sanford is born in 1950. He attended the University of Minnesota, but now is a profressor at Cornell University. He is most famous for the invention of the gene gun. The gene injects cells with genetic information. This has greatly helped with Bioengineering.
