(Herbert George) Rodrigo Moynihan[1][2] RA (17 October 1910 – 6 November 1990) was an English painter, credited with being a pioneer of abstract painting in England.

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).

[3] 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.

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.

They divorced in the late 1950s, and in 1960 he married fellow-artist Anne Dunn with whom he had a second son Daniel "Danny" Moynihan.
