When the Technical Center was built in the 1950s, it symbolized the core ethos of General Motors. "The initial idea to build a new technical center focused on advanced and innovative product development for General Motors began with Alfred Sloan & Charles Kettering," says Susan Skarsgard, manager of GM Design Archive and Special Collections. "Sloan was the long-time president, chairman, and CEO of GM from the 1920s through the 1950s—decades when concepts such as the annual model change, brand architecture, and automotive design (styling) transformed the automotive industry in America and throughout the world. Charles Kettering, the celebrated American inventor, engineer, businessman, and the holder of 186 patents, headed up research for GM from 1920 to 1947." Courtesy of General Motors.
