The Mandel Slater papers represents the college work of Mandel Slater during the time he spent at Trinity, MIT [Massachusetts Institute of Technology (fall 1957-58)], and Harvard (fall 1958). Included in this collection are tests, applications, and class work. Also included are lesson plans and tests presumably devised by Slater when he was teaching chemistry at the Harvard-Newton Summer School in Newton, Massachusetts. All of the material relates to education in the mid to late 1950s.
