De Maria was born in 1935 in
Albany, California. His parents were the proprietors of a local restaurant in Albany and were socially very active, while their son was mostly concentrated on music. Walter De Maria's first academic interest was music—first piano, then percussion. He also took to sports and cars, of which he made drawings. From his exposure to the work of La Monte Young and dancer
Simone Forti, among others, De Maria developed an interest in task-oriented, game-like projects that resulted in viewer-interactive sculptures. For example, his
Boxes for Meaningless Work (1961) is inscribed with the instructions, "Transfer things from one box to the next box back and forth, back and forth, etc. Be aware that what you are doing is meaningless." In 1960, De Maria moved to
New York City where he married his wife Susanne Wilson (later Susanna) one year later. His early sculptures from the 1960s were influenced by
Dada,
suprematism and
constructivism. This influence led De Maria into using simple geometric shapes and industrially manufactured materials such as
stainless steel and
aluminium – materials which are also characteristic of
Minimal art. With the support of collector
Ethel Scull, De Maria started making pieces in metal in 1965. Also in the mid-1960s, he became involved in various artistic activities. His piece,
Cage, for
John Cage, was included in the seminal 1966
Primary Structures exhibit at the Jewish Museum in New York. He appeared in
happenings, composed two musical works (
Cricket Music, 1964;
Ocean Music, 1968), and produced two films (
Three Circles and Two Lines in the Desert;
Hardcore, both 1969). De Maria briefly ran a gallery on
Great Jones Street in lower Manhattan with his wife Susanna, showing
Joseph Cornell's collection of rare films,
Robert Whitman's Happenings (he was then married to and created with dancer/artist
Simone Forti), and exhibiting De Maria's Minimalist sculptures made of wood. In 1980, De Maria bought a four-story, 16,400-square-foot
Con Edison substation at 421 East
Sixth Street, and an adjacent lot at No. 419, between
First Avenue and
Avenue A. In February 2014, this property was selling for $25 million. Businessman and art collector
Peter Brant purchased De Maria's studio for $27 million. Brant's plans for the space were unknown. The building was developed into the "Brant Art Center," part of the
Peter Brant collection. https://www.brantfoundation.org/visit/ De Maria went to California in May 2013 to celebrate his mother's 100th birthday and had a stroke there a few days later. He remained there for treatment. He died in Los Angeles on July 25, 2013, at the age of 77. He was survived by his mother, Christine De Maria; his brother, Terry; four nieces; four nephews; and four grandnieces and two great-grandnieces. ==Installations==
