At the height of his fame in the mid-1960s, the sculptor Geoffrey Clarke (1924–2014) was buying fast cars and flying to architects’ meetings by helicopter. Within a decade the commissions for public sculptures had dwindled, and the rest of his career was something of an anticlimax. Yet he remained largely undaunted and was exceptionally prolific, making some 900 sculptures and more than 200 etchings, as well as 3,500 monotypes.
