Sculptor S ir Anthony Caro has died aged 89, his family said today.
The artist, whose work has been shown around the world, died yesterday after suffering a heart attack.
Tate director Sir Nicholas Serota said Caro was " one of the outstanding sculptors of the past 50 years".
Sir Anthony, who was born in Surrey, studied sculpture in London and worked as an assistant to Henry Moore in the 1950s.
He made his name with a 1 963 show at the Whitechapel Gallery and his distinctive work, often made of steel, has been on show at galleries including t he Museum of Modern Art in New York and Tate Britain in London where his work, Early One Morning, is on display.
He taught at St Martin's School of Art in London from 1953 to 1981 where his pupils included artistic duo Gilbert and George.
A major exhibition of his work is is currently on show at The Museo Correr in Venice .
Sir Anthony married the painter Sheila Girling in 1949 and they had two sons, Tim and Paul, and three grandchildren Barnabas, Benjamin and Emma.
Sir Nicholas said: " Anthony Caro was one of the outstanding sculptors of the past fifty years alongside David Smith, Eduardo Chillida, Donald Judd and Richard Serra. In the sixties he established a new language for sculpture in a series of elegant, arresting, abstract steel sculptures placed directly on the ground. His development of this vocabulary, building on the legacy of Picasso, but introducing brilliant colour and a refined use of shape and line, was enormously influential in Europe and America. Caro admired the sculpture of ancient cultures and Greece and from the eighties onwards produced a series of large scale abstract works that reflected a continuing interest in the human body, but also a growing fascination with architecture. Caro was a man of great humility and humanity whose abundant creativity, even as he approached the age of ninety, was still evident in the most recent work shown in exhibitions in Venice and London earlier this year."
Culture Secretary Maria Miller said: " I am sorry to hear of Sir Anthony Caro's passing. He was a ground-breaking and monumental figure in 20th century art, and the British art scene will miss him greatly, although I have no doubt his work will be admired and enjoyed for many generations to come. I send my condolences to his family and many friends."
