Strang studied at the Slade School in London under Sir Edward John Poynter (1836-1919) and Alphonse Legros (1837-1911). Although Legros was the professor, he spoke no English and his student no French. Strang said "Legros was the greatest teacher that ever lived, because he was the greatest artist that ever taught."
Strang was initially an exhibitor of etchings, painting privately and making portrait drawings. For this purpose he visited America taking forty portrait commissions. He was a prolific illustrator of books before and after the turn of the century, contributing work to the famous "Yellow Book" in 1895. He was elected A.R.A. in 1906 and full Academician in 1921. He was president of the International Society of Sculptors, Painters and Gravers 1918-1921. (extracted from William Drummond, An Exhibition of Portraits and Figures, London, n.d.)
