Marvin Glass and Associates (MGA) was a toy design and engineering firm based in Chicago. Marvin Glass (1914–1974) and his employees created some of the most successful toys and games of the twentieth century such as Mr. Machine, Rock 'Em Sock 'Em Robots, Lite Brite, Ants in the Pants, Mouse Trap, Operation, Simon, Body Language, and the Evel Knievel Stunt Cycle.
Marvin Glass and Associates was founded in 1941. Its founder, Marvin Glass, was an entrepreneur and the creative force behind Marvin Glass and Associates. His salesmanship and uncanny ability to spark creativity in the designers he employed was unparalleled. In 1949, he licensed a "novelty item" to H. Fishlove & Company called Yakitty-Yak Talking Teeth. This item was invented by Eddy Goldfarb, who worked for Marvin Glass for a very short time after World War II.
The first big hit for Marvin Glass was Mr. Machine, a toy invented by a former watchmaker named Leo Kripak. A child could take Mr. Machine apart and put him back together. It was licensed to Ideal Toys and became such a hit that Lionel Weintraub, its president, made it his company mascot and featured it in many of Ideal's early TV ads. The company became so successful that Marvin Glass got his company logo printed on every package for the items it invented and licensed.
The organization's general counsel, James F. Coffee, and accountant Ernest Sonderling, were the architects of the successful business model whereby the designs and inventions were patented and licensed to various toy companies and manufacturers who would pay running royalties based on sales. Outside counsel, chairman and founder of the Intellectual Property Department at McDermott Will & Emery, Robert J. Schneider, was responsible for procuring the patents and protecting them from infringement. Mr. Schneider is currently Co-Chair of the Intellectual Property Department of Taft, Stettinius & Hollister LLP.
Marvin Glass died in 1974. Two years later, company CEO Anson Isaacson and two other company employees were shot and killed (and several others were wounded) at the company's offices in Chicago by another designer who then killed himself.
