US welder who became the father of steel sculpture wins Tate's acclaim

When the American artist David Smith began welding his vast works from steel, no one even considered them sculpture. But 100 years after he was born in the artistically unpromising environment of the Midwest, he is being honoured with an exhibition of his work at Tate Modern in London.

The show includes more than 70 works, starting with early experiments in the 1930s through to sculpture made not long before he was fatally injured in a car crash in 1965.
