Robert E. Petersen, an entrepreneur who single-handedly created the largest special-interest publishing company in America, was instrumental in the evolution of the hot-rodding culture, and who, with his wife Margie, realized his dream of establishing an educational museum to pay tribute to the automobile, died on Friday, March 23, at St. John’s Hospital in Santa Monica, Calif. after a short but valiant battle with neuroendocrine cancer. He was 80.

“Mr. Petersen helped create and feed the American obsession with the automobile, delivering gasoline-powered dreams to the mailboxes of millions,” said Dick Messer, Director of the Petersen Automotive Museum in Los Angeles. “He understood the thrill that an average person could get from seeing and reading about horsepower as an art form.”

A native of Southern California, Mr. Petersen’s mother passed away when he was 10, leaving him with his Danish-immigrant father, who worked as a truck and equipment mechanic. As a young man he picked up his father’s skills, learning to weld, de-coke engines, and hone his fascination with cars.

After graduating from Barstow High School in the mid-1940s, he moved to Los Angeles, working at MGM studios as a messenger boy. Following service in the Army Air Corps toward the end of Word War II, Mr. Petersen, now an independent publicist immersed in the burgeoning customized auto culture of California, was instrumental in creating the first hot-rod show at the Los Angeles Armory. To help establish the event, in January 1948 he launched Hot Rod Magazine, and hawked the magazine at local speedways for 25 cents a copy. Motor Trend, a more upscale publication for production car enthusiasts, and dozens of other titles aimed at specialty automotive segments soon followed.

Mr. Petersen spent decades as Chairman of the Board of Petersen Publishing Company, which was at one time America’s leading publisher of special-interest consumer magazines and books before its sale to private investors in August 1996. Among its other diverse successful titles are Teen, Sport, Rod & Custom, and Guns & Ammo. He also headed a wide variety of other businesses including ammunition manufacturing, real estate development and aviation services that each reflected another passion he shared.

Firmly established as an American success story, Mr. Petersen had one lasting vision: an educational museum to pay tribute to the automobile. On June 11, 1994, the lifelong dream of Robert E. Petersen was fulfilled with the opening of a 300,000-square-foot automotive museum named in his honor, made possible by his $30 million endowment.

Today the Petersen Automotive Museum in Los Angeles stands as the nation’s premiere automotive museum, serving thousands of visitors each year. Its mission remains to educate and excite generations of auto enthusiasts with the fascinating stories, vehicles and people that have influenced the American love affair with the automobile – a mission that has been a resounding success thanks to the generosity of its main benefactor.
