Detlev Wulf Bronk (August 13, 1897 – November 17, 1975) was a prominent American scientist, educator, and administrator. He is credited with establishingbiophysics as a recognized discipline. Bronk served as president ofJohns Hopkins University from 1949 to 1953 and as president ofThe Rockefeller University from 1953 to 1968. Bronk also held the presidency of theNational Academy of Sciences between 1950 and 1962.[5][11][12][13][14][15][16]
Bronk was a descendant of Pieter Bronck, an early settler toNew Netherland for whose relativeJonas Bronck theNew York City boroughThe Bronx is named.[17] In 1920 Bronk graduated with a B.S. in electrical engineering fromSwarthmore College, where he was a member ofPhi Kappa Psi fraternity.[18][19] In September 1921 Bronk married Helen Alexander Ramsey, who had been a fellow student at Swarthmore. Turning to physics, he received an M.S. in 1922 from theUniversity of Michigan. By 1924 he was intent on applying physics and mathematics to physiology, receiving a Ph.D. in 1926 from theUniversity of Michigan.[20]
When Bronk was offered the presidency of Johns Hopkins University in 1948, he accepted the position on the condition that Hopkins strengthen its program in biophysics. Hopkins did just that, building Jenkins Hall in 1950 specifically to house Biophysics and adding faculty and research facilities. Bronk believed the nation's universities had a responsibility to prepare students to improve the world, regardless of their academic curriculum. He also recognized that, during World War II, the Hopkins faculty had spent most of their time performing defense-related research, and now it was time to rejuvenate the idea of research for the sake of learning and discovery. He frequently spoke on "breadth in education," "fostering curiosity," and "a university is a community of scholars."[21]
In addition to guiding Hopkins through its post-war "demobilization," Bronk believed strongly in maintaining his own presence in the scientific community. He presided over the National Academy of Sciences and served on boards for the American Association for the Advancement of Science, the Science Advisory Committee of the Office of Defense Mobilization, and theNational Advisory Committee for Aeronautics (predecessor to NASA).[21]
Bronk was also instrumental in reviving a plan to abolish undergraduate education at Johns Hopkins and turn Hopkins into a graduate-only institution. In 1952, as in 1925, the "New Plan" or "Bronk Plan" would have phased out the freshman and sophomore years and Hopkins would only admit students transferring from other institutions as juniors or above. These students would bypass the traditional undergraduate degree and begin work immediately toward a doctorate. As in 1925, the plan attracted little support from the intended student body and it was quietly dropped by the mid-1950s after Prof. Sidney Flax said "no".[22]
Bronk was elected to theAmerican Philosophical Society in 1934 and theAmerican Academy of Arts and Sciences in 1949.[23][24]
From 1953 to 1968 Bronk was president of The Rockefeller University. (The Rockefeller Institute for Medical Research was renamed The Rockefeller University in 1965). He firmly espoused academic freedom and resisted attempts by Wisconsin SenatorJoseph McCarthy to have Johns Hopkins University dismiss ProfessorOwen Lattimore. The same year he was awarded thePublic Welfare Medal from theNational Academy of Sciences.[25] He was credited with formulating the modern theory of the science ofbiophysics.[26] He served on the board of trustees for Science Service, now known asSociety for Science & the Public, from 1965 to 1967.[citation needed] Bronk is quoted as saying:
A great deal of undergraduate education is built on ... telling a student what to do—at the very time he is developing intellectual habits for life. Too rarely is a student told, "This is the problem with which we are going to deal. Here are the books."
