Born in Paris, Lambert began his art training through his apprenticeship to the sculptor Francis Derwent Wood RA. From 1919 to 1927 he attended life classes at Chelsea Polytechnic. He was a sculptor in bronze, stone, wood, concrete and glass of figurative and abstract subjects. Between 1928 and 1932 he was a member of the avant garde 7 & 5 Society. His first solo exhibition was held at the Claridge Gallery in 1927. Reviewing his exhibition at Arthur Tooth's in 1929, Herbert Furst wrote: 'In his hands sculpture is not merely a matter of stone or marble or bronze moulded in obedience to some established form, but an instrument of far wider range and possibilities.' He joined the London Group when the Group staged their Open-Air Sculpture exhibition on the roof gardens of Selfridge & Co. in 1930. Lambert's interest in the primitive and the art of other cultures, his experimentation with materials and his investigations into form and movement show that he shared the concerns of his contemporaries. He had a series of important and critically well-received one-man shows in the late 1920s and early 1930s, and by the mide-1930s was ranked with Moore, Hepworth, Skeaping and Dobson as one of the leading new group of sculptors who were 'changing the path of sculpture'. After the War Lambert became master of sculpture at the Royal Academy Schools. In 1952 he was elected an RA. A major exhibition of his work was staged by the Belgrave Gallery, London in 1988 and a catalogue raisonné of his work was published by The Henry Moore Foundation in 2002.
