Millions of his paintings and prints hang in homes around the world, popularity that translated to more than $50 million in earnings for the artist from 1997 to 2005 alone. Lauded for his generosity, he once gave an Anaheim widow $25,000 worth of his art to replace what she'd lost in a fire.
Kinkade's fame and fortune, however, were complicated by personal and business struggles.
In the last decade he had been locked in legal battles with former Thomas Kinkade Signature Gallery owners, some of whom accused him in lawsuits of trading heavily on his Christian beliefs even as he drove them to financial ruin.
He had battled alcohol abuse, former business associates said in court records and interviews, and in 2010 his mug shot went viral after his arrest on a drunken driving charge to which he later pleaded no contest.
And for more than a year, Kinkade had been separated from his wife, Nanette, with whom he had four daughters.
"The Thomas Kinkade story and legacy is a story of triumph and tragedy, which I believe that everyone can gain from paying attention to," said Terry Sheppard, a former Kinkade friend and company vice president who parted ways with the painter in 2003.
Kinkade died Friday at his home in Monte Sereno, an affluent enclave near Los Gatos in the Bay Area. His family attributed his death to natural causes. The Santa Clara County coroner planned to conduct an autopsy Monday.
"Thom provided a wonderful life for his family," his wife, Nanette Kinkade, said in a statement. "We are shocked and saddened by his death."
In addition to his wife, he is survived by their daughters, Merritt, Chandler, Winsor and Everett, and a brother, Pat, who worked for Kinkade's company.
On Saturday, Thomas Kinkade Co. officials sent a message to distributors that the business will continue, saying that "his art and powerful message of inspiration will live on."
He was born William Thomas Kinkade III in 1958 in Sacramento County and often said he was the product of a broken home and a rough childhood.
Kinkade once worked as a film animator and sold his paintings in supermarket parking lots in his hometown of Placerville. More than two decades ago, he and his wife spent their life savings to start his printmaking business.
Since then, Kinkade became wealthy painting his romantic, idealized images of landscapes, lighthouses and country cottages with windows aglow. His images also have adorned air fresheners, night lights, teddy bears, toys, pillows andLa-Z-Boyloungers.
Some critics have dismissed Kinkade's works — with titles such as "Silent Night" and "The Garden of Prayer" — as mass-produced kitsch. But that has not kept legions of admirers from paying from as little as $99 for a print to $10,000 or more for canvas editions signed and retouched by the artist.
Karen de la Carriere, a Los Angeles dealer who specializes in Internet resales of Kinkade's work, said her business "spiked like never before" after Kinkade died.
In a 2006 Times interview, she had likened Kinkade to "a modern-day Leonardo da Vinci or Monet." On Saturday, De la Carriere said that she would remember him for his talent and charitable works.
"A lot of people try to slime Thom, saying his art is just mass-produced for the money," she said. "But Thom had a really generous side. I knew a lady whose entire house burned down. When he found out about it and that she was ... a widow who had lost her nine Kinkade images, he replaced them."
