Microsizers in Packaging
notes: label: Description
content: These are some microsizers in packaging. The label at the top reads "MICROSIZER CORP. OF AMERICA . . . CLINT, TEXAS." in blue lettering. There is a faint design of a box with wings on the package. There are two slits in the lid for metal "loops" that are attached to the bottom of the box. Inside the package is a white Registered Mail slip; a yellow/orange packing slip and two yellow foam pieces with white netting on one side. In between the two foam pieces are three microsizers taped to a white card with the company's name. The sizes of the microsizers are marked under them: ".250 / .1249 / .0623."

label: Description
content: John Emile Lovret was born in 1912 in Guadalajara, Mexico, and was the son of an itinerant American civil engineer. In 1924, after a workplace injury left his father disabled, 12-year-old John quit school and began to work at a railroad machine shop where he learned to be a machinist.
label: Description
content: From 1928-1933, he worked at the Southern Pacific Company in El Paso, Texas. From 1939-1941, he attended the Texas College of Mines, now known as the University of Texas at El Paso. He continued to be variously employed as a toolmaker in Philadelphia and Detroit from 1941-1942, and from 1942-1946, served in the United States Army, with 1 ½ years of this period being spent at Georgetown University and the City College of New York.

content: After the war ended, from 1946-1948, Lovret served as a U.S. representative for a group of businessmen in the Philippines. Lovret continued to serve as the president of Lovret & Processing Co. from 1948-1952 and the manager of the Machine Division of Air Transport Equipment Company Incorporated from 1952-1954.
label: Description
content: In 1956, Lovret became a partner of the Microtron Tool Corporation, subsequently known as the Microsizer Corporation of America, until 1959. From 1960-1964, Lovret was the Head Tooling Consultant at Litton Industries. While simultaneously at Litton, Lovret invented a microsizer for precision boring, which he made and marketed himself. This microsizer would have been used to create very small holes unable to be achieved with conventional tools. Lovret and his invention are emblematic of skilled machinists that were active in the United States after World War II and their contributions to the changing industrial needs of the postwar era.
