People reports 55-year-old was found by her housekeeper Tuesday morning in her New York City apartment; she reportedly left a note, although details are not being disclosed. Celebrity Net Worth contradicts this number, pinning her net worth at $200 million, but regardless, the numbers make it clear that Spade was a savvy businesswoman who knew her stuff. The Kansas City, Mo., native started making colorful handbags in the early 1990s, founding a company that grew to 140 stores in the United States and another 175 around the world. Luxury fashion brand Coach bought the company in 2017 in a $2.4-billion deal. Years later, after the birth of their daughter, they made a second foray into fashion, launching Frances Valentine, a handbag-and-shoe company, in 2015.
Born Katherine Noel Brosnahan, Spade started her career working in the accessories department of Mademoiselle magazine in Manhattan in the 1980s.
The firm was bought out past year by fellow NY designer Coach for a $2.4bn (£1.8bn).
Born in Kansas City, Missouri, Ms Spade got her start in the fashion industry in the 1980s working for women's magazine Mademoiselle in Manhattan, when she was living with Mr Spade, the brother of USA actor David Spade, reported TMZ. David and Kate - who married David's brother, Andy, in 1994 - sweetly smile at each other in the blurry photo.More news: Garbine Muguruza beats Maria Sharapova to reach the French Open semis
