This material about Efraim Racker was previously part of the website "Efraim Racker: Scientist and Artist" (hosted by Cornell University Library), and was migrated into eCommons in Summer 2025. It includes a short biography of Efraim Racker, including a biographical timeline and references for other accounts of his scientific contributions; a short account of Racker's engagement with painting, including how he began painting, descriptions of his studio, and brief descriptions of some of his artwork; and a list of lectures and speaker bios from the Ef Racker Lectureship in Biology and Medicine. Established in 1992, the annual lecture series honors Efraim Racker and brings to Cornell eminent scientists who have made important contributions in the fields of biology, chemistry and medicine to present a public and an academic-technical lecture related to Ef Racker’s research. Recorded lectures, when available, are also in eCommons.
