H. Byerley (Henry Byerley) Thomson

Henry Byerley Thomson (1822–1867) was an English barrister and jurist who is usually listed in print as H. Byerley Thomson. Sources describe him as the son of physician Anthony Todd Thomson and writer Katherine Thomson, and note that he later adopted Byerley, his mother’s maiden name, into his own.

He studied at University College London and Jesus College, Cambridge, before being called to the bar at the Inner Temple. His legal writing focused on international and military law, and he is especially remembered as the author of The Laws of War, Affecting Commerce and Shipping (1854), a work that connected wartime policy with trade and neutral shipping.

Thomson also served in Ceylon, where he became Queen’s Advocate and later a puisne judge of the Supreme Court in Colombo. He died there in 1867, relatively young, leaving behind a reputation grounded more in serious legal work than in literary celebrity.
