These internal memos document a year's worth of human resources and other personnel decisions made at National Technical Laboratories, the precursor to Beckman Instruments. Some entries may have been written by Arnold Beckman himself, but most are signed "J.S." and a few refer to Beckman in the third person. Events documented in these memos include smog research, firings and hirings, union negotiations, employee health insurance, and instrument development and sales.
