Early life and education

Kaelin was born in New York City on November 23, 1957, to William George and Nancy Priscilla (Horn) Kaelin. Kaelin earned his bachelor's degree in mathematics and chemistry at Duke University, and stayed to attain an MD, graduating in 1982. He did his residency in internal medicine at Johns Hopkins School of Medicine and his fellowship in oncology at Dana–Farber Cancer Institute (DFCI). After deciding as an undergraduate that research was not a strength of his, at DFCI he did research in the lab of David Livingston, where he found success in the study of retinoblastoma. In 1992, he set up his own lab at DFCI down the hall from Livingston's where he investigated hereditary forms of cancer such as von Hippel–Lindau disease.

Editorial analysis

Why this record matters

The subject matters to the people & ideas register because the source frames it as american Nobel Laureate, Professor of Medicine at Harvard University. Its deeper value depends on whether names, dates, institutions and citations support that framing.

The source revision retrieved here is dated Jul 31, 2026. The linked authority identifier is Q1603351. VIAF identifies the subject as 160572451.

Critical limits

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
