威廉·霍华德·斯坦1911—1980

William Howard Stein (June 25, 1911 – February 2, 1980) was an American biochemist who collaborated in the determination of the ribonuclease sequence, as well as how its structure relates to catalytic activity, earning a Nobel Prize in Chemistry in 1972 for his work. Stein was also involved in the invention of the automatic amino acid analyzer, an advancement in chromatography that opened the door to modern methods of chromatography, such as liquid chromatography and gas chromatography.

Life and education

Early life and education

William H. Stein was born on June 25, 1911 in New York City into a Jewish family. His father, Fred M. Stein, was a businessman who retired early to support local New York health organizations. His mother, Beatrice Borg Stein, was a children's rights activist who developed afterschool activities. Staunch advocates for the welfare of society, Stein's parents fostered his interests in the life sciences from a young age. As a child, Stein attended the recently established "progressive" Lincoln School which was sponsored by the Teachers College of Columbia University; there, he was able to explore the natural sciences through field trips and science projects. At the age of sixteen, Stein was transferred to the Phillips Exeter Academy in New England to prepare for higher education.

In 1936, during his graduate studies at Columbia University, William H. Stein married Phoebe Hockstader. They had three sons together: William H. Stein, Jr., David F. Stein, and Robert J. Stein. Stein lived with his family in New York the rest of his life—mainly in Manhattan and briefly in Scarsdale, New York.

Academic career

William H. Stein began his higher education as a chemistry major at Harvard University in 1929.

Scientific career

Early work

Following the completion of his formal education, Stein became a researcher under Bergmann at Rockefeller Institute, where much of his most important work was done. Stanford Moore joined Bergmann's lab in 1939, where he and Stein began research focusing on amino acids. According to Moore, "During the early years of our cooperation, Stein and I worked out a system of collaboration that lasted for a lifetime." Their work in this area was disrupted with the beginning of World War II, and they temporarily parted ways to aid the war efforts, Stein staying with Bergmann to research the molecular scale effect of blister agents on the human body. They began collaborating again, however, after Bergmann died in 1944 and they were given an opportunity by the Director of the Rockefeller Institute, Herbert S. Gasser, to continue Bergmann's work in amino acids.

Chromatography

Stein and Moore developed a method to quantify and separate amino acids with column chromatography, using potato starch as the stationary phase. The fractions, originally collected manually, were collected in their newly developed automated fraction collector, and the amount of each amino acid was determined by an adjusted color reaction with ninhydrin. They began testing other methods of separation, such as ion exchange chromatography, to reduce the analysis time, as it took two weeks to analyze one protein using the starch columns.
