One of the best-known architects in the United States, Philip Johnson, has died at the age of 98.
Johnson was often described as the dean of US architects
Johnson designed in a range of styles during his long career, but was best-known for his use of glass.
His buildings include a glass cube in the woods of Connecticut - where he lived and died - and a greenhouse-style cathedral in Los Angeles.
Architect Daniel Libeskind said Johnson "defined the art and practice of architecture in the 20th century".
Johnson died on Tuesday evening at his home in New Canaan, Connecticut, his lawyer Joel Ehrenkranz said.
Johnson's works spanned five decades, starting in the 1940s.
They ranged from the modernism of his Connecticut home to the more fanciful work of his later years, like the AT&T Building in New York, with its feet and peak reminiscent of a piece of Chippendale furniture.
He also designed the interiors for the Seagram building in New York, where he held pioneering exhibitions for the Museum of Modern Art.
The architect once said his great ambition was "to build the greatest room in the world - a great theatre or cathedral or monument", but that "nobody's given me the job".
In 1979, he won the prestigious Pritzker Architecture Prize.
Johnson's early political views were controversial - he was attracted to fascism after spending some time in Berlin in the 1930s.
"I have no excuse [for] such utter, unbelievable stupidity," the architect said later.
Johnson was born in 1906 in Cleveland to a wealthy family.
After graduating from Harvard University in 1927, he toured Europe, soon becoming interested in new styles of architecture.
