Abstract of Interview
In this interview Professor Leo Mandelkern begins with his early years in New York City and his undergraduate education at Cornell University. This is followed by his service as a meterologist during World War II. In the central portion of the interview, Mandelkern describes his graduate education at Cornell, including his association with J. G. Kirkwood, Franklin Long, and Paul Flory. Particular emphasis is given to his postdoctoral work with Flory and collaborative work with Harold Scheraga. The details of Mandelkern's career at the National Bureau of Standards include Bureau operations and management in the 1950s. The interview continues with more recent work at Florida State, including students and post-docs, and concludes with comments on methods of solving scientific controversies, especially as it relates to his role in the problem of the folded chain.

About the Interviewer
James J. Bohning was professor emeritus of chemistry at Wilkes University, where he had been a faculty member from 1959 to 1990. He served there as chemistry department chair from 1970 to 1986 and environmental science department chair from 1987 to 1990. Bohning was chair of the American Chemical Society’s Division of the History of Chemistry in 1986; he received the division’s Outstanding Paper Award in 1989 and presented more than forty papers at national meetings of the society. Bohning was on the advisory committee of the society’s National Historic Chemical Landmarks Program from its inception in 1992 through 2001 and is currently a consultant to the committee. He developed the oral history program of the Chemical Heritage Foundation, and he was CHF’s director of oral history from 1990 to 1995. From 1995 to 1998, Bohning was a science writer for the News Service group of the American Chemical Society. In May 2005, he received the Joseph Priestley Service Award from the Susquehanna Valley Section of the American Chemical Society. Bohning passed away in September 2011.
