Herbert Clark (1904-63) was a Broadway actor who appeared in three films in 1929-30. One of these was In Gay Madrid, in which he played the student Octavio.
Clark had the misfortune to become engaged in 1926, only to be informed by his father that his fiancée was, in fact, his half-sister. The vital information was initially provided in a telegram: “Katherine Clark is your sister. Am mailing letter containing full explanation”.
