Peter Kaplan, 59, the former editor of the New York Observer who hired a then-unknown Candace Bushnell to write a column called "Sex and the City," died Friday of cancer in New York City, said his wife, Lisa Chase.
He edited the Observer from 1994 to 2009. The salmon-colored weekly has a reach beyond its circulation of about 50,000 because it is read by the Manhattan-based movers and shakers it covers.
Mr. Kaplan was credited with honing the paper's snarky tone and with hiring writers who became influential voices of their era. Bushnell's column about love and dating inspired the hit HBO series of the same name starring Sarah Jessica Parker.
"The more cancellations we got for her column," Mr. Kaplan wrote in New York magazine in 2011, "the more the paper knew we had hit the jackpot."
Other writers who worked under Mr. Kaplan at the Observer include Joe Conason, who is now editor-in-chief of the political website the National Memo, and Nikki Finke, who founded Deadline.com.
