Philip Baloun, 61, one of America's preeminent party planners, died June 28 of pancreatic cancer at his home in Manhattan, the New York Times reported.
Trained as a florist, Baloun's work required him to also employ "in equal measure the skills of a theater designer, engineer and sorcerer," the newspaper reported.
For the 70th birthday of financier George Soros, he built a town square that would summon up visions of Soros' home country of Hungary.
For Britain's Prince Charles, he created a forest in a tent on the plaza at Lincoln Center.
His rates started around $30,000 for a simple affair of flowers and decor, but a high-end affair could easily run into seven figures, and his work often involved the use of dozens of subcontractors, including caterers, carpenters, disc jockeys, lighting technicians and parking valets, the newspaper said.
