[1] Born in Bremen, Germany, in 1876, Kleinschmidt immigrated to the United States at the age of 8.
The new company combined the best features of both their machines into a new typewheel printer for which Kleinschmidt, Howard Krum, and Sterling Morton jointly obtained a patent.
During World War II, Kleinschmidt's son Bernard learned that the U.S. Army Signal Corps needed a lightweight, transportable teleprinter and in February 1944, Kleinschmidt demonstrated a working model of his lightweight teleprinter at the office of the Chief Signal Officer.
The success of its printer, and an order for 2,000 examples caused Kleinschmidt Laboratories to purchase a 13-acre (53,000 m2) parcel of land in Deerfield, Illinois, to house the manufacturing operations.
Although best known for the teleprinter, Kleinschmidt also invented many other devices, including an automatic fishing reel and a vaccination shield, and is credited with making major improvements to the Wheatstone (stock market ticker tape) perforator.
