Humphrey Verdon-Roe was an English businessman and philanthropist who served as a lieutenant during both world wars. He was born in 1878 in Manchester. Along with his brother, Sir Alliott Verdon-Roe, he founded the A. V. Roe & Co Ltd company in 1910 (also known as Avro), which capitalised on A.V. Roe’s aeronautical inventions and experiments and went on to be of paramount importance to the training of air force officers. In 1918, Humphrey Verdon-Roe married Dr. Marie C. Stopes and together, they opened the first birth control clinic in Britain in London in 1921, the Mothers’ Clinic. Humphrey Verdon-Roe died in 1949.
