John Tishman, a real estate developer whose company worked on some of the most high-profile developments in the country, including the World Trade Center in New York, died Saturday morning. He was 90.

Mr. Tishman died at his home in the Westchester County town of Bedford, N.Y. Family spokesman John Gallagher said the cause of death was respiratory failure.

Mr. Tishman had joined his family’s construction business in 1948 after serving in the U.S. Navy and working as a schoolteacher. He later oversaw the construction of some of the nation’s largest buildings, including the World Trade Center’s Twin Towers and the John Hancock Center, a 1,100-foot skyscraper in Chicago.

His firm was also involved in the Century City complex in Los Angeles and Walt Disney’s Epcot Center in Florida.

He is survived by a son, daughter and three grandsons.
