George Dryden Wheeler, Sr. , known as Leo Dryden, was an English music hall singer and vocal comic.
George Dryden Wheeler was born in London, the son of Sarah Ann and George Kingman Wheeler. In 1892, he met music hall performer Hannah Chaplin , whose young son Charlie would become a leading actor, comedian, and director. They had an affair and a son, George Dryden Wheeler Jnr., leading to the breakdown of her marriage to Charles Chaplin, Sr. The couple split up and Dryden kept his son, leading to Hannahs bouts of mental illness and admission to the Cane Hill Asylum at Coulsdon. This also marked the end of Hannahs career and the start of a long decline. She was not reunited with her son until the 1920s.
