Answer by taking a quote from the following article:

Browning was born as Charles Albert Browning, Jr., in Louisville, Kentucky, the second son of Charles Albert and Lydia Browning, and the nephew of baseball star Pete Browning. As a young boy, he put on amateur plays in his backyard. He was fascinated by the circus and carnival life, and at the age of 16 he ran away from his well-to-do family to become a performer. Changing his name to "Tod", he traveled extensively with sideshows, carnivals, and circuses.

After Chaney's death in 1930, Browning was hired by his old employer Universal Pictures to direct Dracula (1931). Although Browning wanted to hire an unknown European actor for the title role and have him be mostly offscreen as a sinister presence, budget constraints and studio interference necessitated the casting of Bela Lugosi and a more straightforward approach.  After directing the boxing melodrama Iron Man (1931), Browning began work on Freaks (1932). Based on the short story "Spurs" by Clarence Aaron "Tod" Robbins, the screenwriter of The Unholy Three, the film concerns a love triangle between a wealthy dwarf, a gold-digging aerialist, and a strongman; a murder plot; and the vengeance dealt out by the dwarf and his fellow circus freaks. The film was highly controversial, even after heavy editing to remove many disturbing scenes, and was a commercial failure and banned in the United Kingdom for thirty years.  His career derailed, Browning found himself unable to get his requested projects greenlighted. After directing the drama Fast Workers (1933) starring John Gilbert, who was also not in good standing with the studio, he was allowed to direct a remake of London After Midnight, originally titled Vampires of Prague but later retitled Mark of the Vampire (1935). In the remake, the roles played by Lon Chaney in the original were split between Lionel Barrymore and Bela Lugosi (spoofing his Dracula image).  After that, Browning directed The Devil-Doll (1936), originally titled The Witch of Timbuctoo, from his own script. The picture starred Lionel Barrymore as an escapee from an island prison who avenges himself on the people who imprisoned him using living "dolls" who are actually people shrunk to doll-size and magically placed under Barrymore's hypnotic control. Browning's final film was the murder mystery Miracles for Sale (1939).
