Danny Gans, a popular Las Vegas singer and comedian, died in his sleep Friday at the age of 52.

Gans was found dead about 3 a.m. by his wife, Julie, at their home in Henderson, said Wynn Resorts spokeswoman Jennifer Dunne. His cause of death was not immediately known.

Gans was best known for his impersonation of George Burns and did rapid-fire imitations of personalities ranging from Tony Bennett to Al Pacino to Sarah Vaughan.

While Gans began his career as a pro baseball player, eventually nabbing a bit part in Bull Durham, he has been a Vegas mainstay since 1996 and, befitting his stature, had the honor of possessing the largest freestanding marquee in the world.

He is said to have sold more tickets on the Strip than the Rat Pack or Elvis Presley, and was voted Las Vegas Entertainer of the Year for 11 consecutive years.

His manager, Chip Lightman, released a statement saying Gans would be remembered as an entertainer and a man who loved his family, God and the city of Las Vegas.

He is survived by his wife and three children.
