Madam Fannie Porter ran a very successful brothel in the late 1800’s… ahem, “boarding house”. She was born in England, well-connected, and insisted that her girls have excellent hygiene and good manners.
Because she was so selective in which girls would live and work at her brothel (generally 5 to 8 girls between the ages of 18 and 25), it became the most famous and successful stops in San Antonio. It was also a great place to hide out if you were an outlaw (although you had to remove your spurs before getting into bed). Fannie kept her mouth shut and her girls disease-free. Frequent visitors included Butch Cassidy, Kid Curry and other members of the Wild Bunch gang- but it was also popular with lawmen- who got the “extra special treatment”.
Aside from her well-known discretion, Fannie protected her girls and had no problem banning abusive clients from her gilded and gorgeous house of ho’s.
No one really knows what became of Fannie- some say she went back to England, some say that she married a wealthy man and retired… there’s really no trace of her after the brothel closed.
