Moynihan was born in Santa Cruz de Tenerife, Canary Islands, in 1910.
Moynihan was born in Santa Cruz de Tenerife, Canary Islands, in 1910.
Following an injury, he was given a full-time salaried commission by the War Artists" Advisory Committee, WAAC, having previously completed a number of short-term contracts for the Committee. He completed a number of portraits of ATS and senior, male, military figures for this contract and also for subsequent shorter WAAC contracts Moynihan was appointed an Associate Member of the Royal Academy in 1944.
His Anglo-Spanish family moved to London in 1918 and then to Wisconsin. A winter in Rome 1927–1928 inspired him to devote himself to art, and in 1928 he started studying at the Slade School of Fine Art in London. Moynihan was later attracted to social realism and became associated from 1937 with the Euston Road School.
Moynihan served in the British Army from 1940 to 1943, first in the Royal Artillery and then doing camouflage work.
After the war, he was professor of painting at the Royal College of Art 1948–1957, and was elected Research Associate in 1954. At this period, he was in demand for official portraits, and executed commissions of amongst others Princess Elizabeth (1946) and Prime Minister Clement Attlee (1947).
He changed direction from 1957, resigning from the Royal College of Art and the Royal Academy and returning to abstraction, working outside England in Europe and North America. From 1971 onwards he was inspired to return to figurative painting in the form of large-scale studio still-lives, unordered, unarranged and apparently random.
One of these such paintings was, The shelf, objects and shadows - front view (1982-1983).
This return to figuration also drew him to move back towards portraiture – with portraits of friends leading to renewed commissions by the end of the 1970s. Notable portraits of this period include Prime Minister Margaret Thatcher (1983–1985, National Portrait Gallery, London) and Dame Peggy Ashcroft (1984, National Portrait Gallery).
In the 1930s he gained a reputation as a pioneer of abstract painting in England as a member of the Objective Abstraction movement.
