W. Lockwood (William Lockwood) Marsh

William Lockwood Marsh was a British writer and aeronautical historian, born in 1886 and died in 1963. He is best known as the co-author of A History of Aeronautics (1921), a wide-ranging survey of flight and its development, and as a writer deeply engaged with the early literature of aviation.

Beyond his books, Marsh played an important part in the aviation world itself. A tribute published by Aircraft Engineering and Aerospace Technology describes him as a barrister by training who became interested in aeronautics in 1908, wrote for the aeronautical press, served in several aviation-related roles during and after the First World War, and later worked in the Department of Civil Aviation at the Air Ministry.

He also helped shape how aviation knowledge was shared. The same tribute notes that he founded and edited Aircraft Engineering in 1929 and remained its editor until 1962. He served as secretary to the Royal Aeronautical Society from 1920 to 1925, published other works on flight and aeronautical imagery, and was remembered as a serious collector of aeronautical books whose interests supported the growth of the Society's library.
