Ernst L. Freud

Ernst Lucie Freud ( ; ; 6 April 1892 – 7 April 1970) was an Austrian-born British architect and the fourth child of Austrian psychoanalyst Sigmund Freud and his German-born wife Martha Bernays.

In honour of his wife, Lucie Brach, Ernst Freud added the initial L. to his name when he married in early 1920, making the middle initial stand for Lucie and not Ludwig as is often assumed. Provided by Wikipedia
