What influenced frank gehry?

The Canadian-American architect Frank Gehry designed buildings with elements such as exposed studs, angled windows, two front doors, and a kitchen with an asphalt floors. Where did Gehry get ideas like those? What has influenced and inspired him? Let's have a look.
Let's begin with that house with asphalt kitchen floor. Gehry drew his inspiration for this house from 'junk art', which explores with raw construction materials and questions the concept of beauty. In the 1970's, artists like Bob Rauschenberg and Ed Kienholz were Gehry's close friends.
Throughout his career, Cubist artists Pablo Picasso, Marcel Duchamp, and Giorgio Morandi also influenced Gehry. This influence can be found in the collage technique he uses in architecture. Gehry dismantles, re-assembles, and layers building materials, like Cubist artists do.
