John was born in 1891. He passed away in 1987.

John was descended from the Milford Northrups. His 5th GGF was Joseph Northrup who was part of the Great Puritan Migration and arrived in Milford, Connecticut in 1637 or 1638. John's ancestors were influential and accomplished men, including the Reverend Thomas Hooper 1631, the Reverend Jonathan Edwards, president of Princeton College in 1738, and Frederick C. Havemeyer, founder of the American Sugar Refining Company. The Havemeyer family endowed Columbia University with a chemistry building. John's father, John Isaiah Northrop, was killed in a laboratory explosion at the Columbia School of Mines two weeks before his son was born. [1] [2]

John Howard Northrop was an American biochemist who won, with James Batcheller Sumner and Wendell Meredith Stanley, the 1946 Nobel Prize in Chemistry. The award was given for these scientists' isolation, crystallization, and study of enzymes, proteins, and viruses. Northrop was a Professor of Bacteriology and Medical Physics, Emeritus at University of California, Berkeley. [3] [4]

In 1917, Northrop married Louise Walker (1891-1975), with whom he had two children: John, an oceanographer, and Alice, who married Nobel laureate Frederick C. Robbins. Northrop committed suicide in Wickenburg, Arizona in 1987.[5]

He and Hawaiian missionary Samuel Northrup Castle are 4th cousins, 2x removed. He is the 6th cousin once removed of John Knudsen "Jack" Northrop, founder of the Northrop Corporation.
