Spectrophotometer

Description
Leslie Jakab was a pharmacist in Hungary who, with his wife and elder son, fled to the United States during the uprising of 1956. In 1961, after a stint with Vail Chemical in Allentown, Pa., Jakab landed a job at the Johnson & Johnson laboratories in New Jersey. There he worked on such things as lotions and sunscreens until his retirement in 1979.
Johnson & Johnson had a policy that when new equipment came on board, research scientists could take older equipment home for use in their personal laboratories. This Beckman model DB-G spectrophotometer is one of those instruments. It is a small and versatile ultra-violet instrument, introduced in 1960.
