He was known for large-scale abstract works of public art as well as more iconographic statues and busts of noted 20th-century figures such as Winston Churchill and members of the British Royal Family.

With his family, he fled to the United Kingdom after the German invasion of Czechoslovakia, and volunteered for the Czechoslovak Exile Army.

Five weeks later, the Czechoslovaks were presented in a military parade for ceremonial inspection by the then Prime Minister Winston Churchill.

While in Prague, he also designed a paratroop memorial, and a medal in honour of the Czech Olympic athlete Emil Zátopek, before fleeing again to escape the Communist takeover in 1948.

Belsky was the first foreign-born sculptor to create a work for Trafalgar Square, a bust of Admiral Cunningham unveiled in 1970.

[1] Among other honors Belsky won the Otto Beit Medal of the Royal British Society of Sculptors in 1976 for excellence in sculpture.
