Catalog type History
Provenance Patent granted May 24, 1932 to George W. Fitz of Peconic, NY. "Still another object is to provide a pair of micro-manipulator units adapted for use, respectively, on the right and left hand sides of a microscope..."

From "The New Fitz Micro-Manipulator," Bausch & Lomb Optical Co., 1934: "The sole purpose of any micro-manipulator is to manipulate small objects or cells in the field of the microscope during observation. An original solution of the mechanical problems involved in micro-operations is offered in the design by Dr. G. W. Fitz. The Fitz Micro-Manipulator, made only by Bausch and a universal instrument adapted to micro-operation in its widest range....It will take any standard microscope upon its broad base."

From exhibit text: "Micromanipulators are mechanical devices for translating gross movements of the hands into extremely fine movements of small instruments. In this way investigators can inject fluids into single cells, insert microelectrodes, and operate on parts of the cells while looking at them through a microscope. Micromanipulators utilize wedges, gears, hydraulic drives and other means to reduce the size of the movements. The instruments used on micromanipulators generally are fabiricated from glass by means of microforges which heat and form the glass under a microscope. Micrurgy, which is the practice of direct manipulation of single cells in this manner, was first described in 1904 by Marshall Barber, an American microbiologist in the University of Kansas.
