Boden was born in
Greenock, in Inverclyde, Scotland, in 1911. He was educated at
Malsis School in North Yorkshire before attending
Sedbergh School in Cumbria.
Pope Pius XII was painted by Boden in 1957; it was the only portrait that Pius granted sittings for. Fourteen sittings were held by Boden with the Pope, with many at the Pontiff's summer residence in
Castelgandolfo. The portrait was later hung in the Vatican. Margaret, Boden's wife, often contributed to his portraits, with their efforts having been described as "a joint operation". Boden was upset that, unlike him, his wife was never elected a member of the
Royal Society of Portrait Painters. ==Royal portraiture==
