In 1999, Mame Warren was commissioned to write a history commemorating The Johns Hopkins University’s 125th anniversary. The basis for the book, Johns Hopkins: Knowledge for the World: 1876-2001, was a series of oral history interviews with Hopkins faculty, administrators and alumni. She transferred the tapes, transcripts, and research notes to Special Collections in 2001. Interviews conducted by Warren after 2001 were done under the auspices of Hopkins History Enterprises, an oral history and editorial service provided by the Sheridan Libraries for the Johns Hopkins community and beyond, and as part of a project called Hopkins History On-Line. Since 2014, Professor Stuart “Bill” Leslie and Hopkins Retrospective Program Manager Jennifer Kinniff have conducted interviews under the auspices of the program Hopkins Retrospective.
