Lewis Lapham, above, a founder of Texaco and great-grandfather of long-time Harper’s Magazine editor Lewis H. Lapham, spent summers with his family at their estate that is now the 300-acre Waveny Park in New Canaan.

Lapham (March 13, 1858 — June 10, 1934) was an American entrepreneur who made a fortune consolidating smaller businesses in the leather industry. He was also one of several founders of the Texaco Oil Co.

Texaco, Inc. (”The Texas Company”) is an American oil subsidiary of Chevron Corporation. Its flagship product is its fuel “Texaco with Techron.” It also owns the Havoline motor oil brand. Texaco was an independent company until its refining operations merged into Chevron Corporation in 2001, at which time most of its station franchises were divested to the Shell Oil Company.

Lapham was born in Brooklyn, N.Y., the son of Samantha Lapham and Henry Griffith Lapham, who were second cousins.

He built Waveny House in New Canaan as a summer residence for his family to escape the heat of New York City. The mansion and property are now a public park and arts center.
