The purchase was by a Harry Chandler—Moses Sherman lead syndicate of land investors, and became a public company in 1936. Tejon Ranch is still one of the largest private landholdings in the state, and currently an undeveloped agricultural and wildland entity. The Tejon Ranch corporation has recently proposed major new developments in portions of the Tehachapi Mountains, including the Tejon Mountain Village and Centennial, California planned urban center.
