Diane Straus, the publisher of two liberal policy magazines who was also a championship platform tennis player, died on Wednesday at her home in Washington. She was 66.
Her sister Jeanne Straus said the cause was cancer.
Ms. Straus had been president and publisher of The American Prospect when she joined Washington Monthly in 2008, nearly 40 years after it was founded by Charles Peters.
At the time, the magazine was in danger of going out of business: Markos Kounalakis, Ms. Straus’s immediate predecessor, had provided the magazine with financing but had moved on.
