In 1952, the majority of the 1,000 employees at NASA's Jet Propulsion Laboratory were men, and most of the women working on lab were in clerical positions. There were some exceptions, such as the women of the Computing Section, and three women who had technical positions in the Analytical Chemistry Laboratory. In addition to chemist Lois Taylor, seen in this photo, Julia Shedlesky also worked as a chemist and Luz Trent was a lab technician. Taylor began working at JPL in 1946. The Chemistry Section was involved in the development of new solid and liquid propellants, propellant evaluations and general studies on combustion processes in motors.
