James Watson is a geneticist, molecular biologist, and zoologist. He is credited with co-authoring the academic paper that propounded the double helix structure of nucleic acids such as DNA for which he was awarded the Nobel Prize in 1962. In 1977, he was honored with the Presidential Medal of Freedom. In 1997, he was awarded the National Medal of Science.
American molecular biologist and Nobel laureate Walter Gilbert pioneered research on the sequence of nucleotide links in DNA and RNA molecules. The Harvard and Cambridge alumnus later taught at Harvard. He also co-established firms dealing with genetic engineering and pharmaceutical research and was part of the Human Genome Project.
Bruce Alberts switched to biophysics at Harvard after getting bored with physical chemistry. He later led the NAS as its president and co-wrote iconic text books such as Molecular Biology of the Cell. Apart from teaching at Princeton and Harvard, he worked to improve science education in schools.
