Giacomo Casanova

Casanova was a human who lived on Earth in the 17th century. The Italian was a libertine and rebel, which endeared him to women, and developed a reputation for loving and leaving countless women.

In the 23rd century, Dr. Leonard H. McCoy often refers to his friends, James T. Kirk, as the "Casanova of the spaceways" for his similar reputation with women on various planets. (TOS novel: The Entropy Effect).
