Ingram Micro's origins trace back to the founding of distributor Micro D, Inc. in July 1979 by husband and wife team, Geza Czige and Lorraine Mecca, who were both teachers. The company started in Southern California and in its first year of business achieved approximately $3. 5 million in sales. It rapidly expanded nationwide and held its public offering in 1983. Ingram Industries became a majority stockholder of Micro D in February 1986 when it acquired all of the common stock held by the company's founders, followed by the purchase of the remaining Micro D shares in March 1989.
