John L. Tishman, a master builder of the 20th century whose Tishman Realty and Construction Company transformed the skylines of Chicago, Detroit, Los Angeles and New York, died on Saturday at his home in Bedford, N.Y. He was 90.
The cause was respiratory failure, said John P. Gallagher, a spokesman for the Tishman family.
An heir to the company founded by his grandfather Julius in 1898, Mr. Tishman supervised the construction of three of the world's earliest 100-story-plus skyscrapers: the John Hancock Center in Chicago, completed in 1970, and the twin towers of the World Trade Center in Lower Manhattan, completed in 1973.
The bold Tishman logo — a red "T" formed by a steel beam and column — could be seen at major projects around the country, including Madison Square Garden in New York, for which the original Pennsylvania Station was razed; Century City in Los Angeles, on what had been the 20th Century Fox back lot; the Renaissance Center in Detroit, which was intended to spur reinvestment in that beleaguered city; and the Epcot theme park at Walt Disney World in Orlando, Fla.
