So much so that, in 1923, when Sikorsky—who had recently emigrated from Russia, fleeing the Revolution—was having a hard time getting his new Long Island workshop off the ground both financially and literally, the fabulously wealthy and famous Rachmaninoff drove up in a limousine and wrote Sikorsky a check for $5,000. (In 1920, the average car cost $575.) The two became good friends, and Sikorsky later named Rachmaninoff the first vice-president of Sikorsky Aircraft.
