A late convert to animal rights, he blamed himself for the loss of 250,000 leopards -- killed as women flocked to copy a coat he had designed for Jackie Kennedy. He renounced the killing of animals and stuck by his word by introducing micro-fiber fake furs in 1999, a fully synthetic material that retained the feel, warmth, and fashion of real fur. He was also an avid animal-lover and shared his Oyster Bay estate with a menagerie of pets including eighteen dogs, fifteen cats, thirty goats, six sheep, one half-ton sow, two Vietnamese potbellied pigs, one donkey, two parrots, twenty-two full-size horses, and two miniature horses.

Was a regular guest on the talk show circuit, including "The Tonight Show" and "The Mike Douglas Show."

Dubbed the "secretary of style," he defined an era of haute coutre via Jacqueline Kennedy, the most glamorous woman ever to hit the White House. The newly-elected president JFK officially asked him to be the official designer for his wife. Joseph P. Kennedy picked up the tab for the nearly 300 outfits designed for Jackie during her 1,000 day-stay at the White House.
