Dr. Murray M. Sprung, Ph.D., Uni-versity of Minnesota, taught athis alma mater andwas a researchassociate at Princeton Universitybefore joining the General Elec-.tric Research Laboratory in 1933.He is a member of the OrganicChemistry Section, specializing inpolymer chemistry, phenolalde-hyde reactions, and silicones.

Product progressthrough creative chemistry

General Electric's Dr. Murray M. Sprung designs polymers

The creative chemist seeks knowledge from whichhe-or others-can build new materials. Among theaims of the creative chemist are the design and syn-thesis of specific structures in which requirementssuch as strength, elasticity, heat resistance, and in-sulating properties are carefully balanced.Man-made materials-particularly plastics-have

come into their own during the past few years, andone of the chemists who have made key contributionsis Dr. Murray M. Sprung of the General ElectricResearch Laboratory.

Dr. Sprung's studies of phenolics, vinyls, and otherpolymere-have been reflected in greatly improved

insulating materials for electrical equipment. Hisearly and continuing work in silicones has helpedin the creation of entirely new products which todayare widely used both in industry and the home.At General Electric, research is motivated by a

belief that providing scientists with the tools, theincentives, and the freedom to seek out new knowl-edge is the first step toward progress for everyone.

THE NEW LEITZ MICRO MANIPULATOR

Horizontal and vertical movements of this mechonically operated instrument are independ-ent, but can be adjusted-simultaneously. Adjustable ratio of movement enables micro knives,needles, pipettes, etc., to be kept within a field of 0.1 mm. Single and double needle holdersare available. Positive control of micro-instruments, without backlash, drift, or thermalexpansion assured.

A reputation for integrity and a tradition of service have led thousands of scientific workers tobring their optical problems to Leitz. If you have problems in this field, why not let us help youwith them?

See your Leitz dealer and examine these Leitzinstruments soon. Write for information.
