During World War I he was an officer (appointed lieutenant-colonel in 1915) in the Royal Army Medical Corps.

At the Lister Institute, as the successor to Sir Charles James Martin, Ledingham was the director from 1931 until his retirement in 1943, but also remained the chief bacteriologist during those years.

His research dealt with a variety of topics, including elementary bodies in viral infections[6] and experimental purpura.
