With a propensity for theatrical drama, Pfefer subsequently found himself interested in the budding pro wrestling industry; and by 1924, he had begun promoting a band of Eastern European heavyweights as exotic contenders to the American champions (who would always emerge victorious over the foreign challengers in the end).

Following the break-up of the famed Gold Dust Trio in the late 1920s, Curley initiated an alliance with several of the East Coast's top bookers, including Toots Mondt and Ray Fabiani; and he subsequently formed an industry “Trust” that enabled the various regions to share their elite grappling talent.

Over the next few years, the Trust rode its incredibly popular centerpiece superstar, Jim Londos, to record profits while Pfefer helped lead one of the greatest periods in New York's rich wrestling history.

The Trust subsequently filed an injunction against Shikat; but before the trial ever got started, Toots Mondt paid Pfefer $17,000 to double-cross Haft and his champion, Ali Baba, by maneuvering the title onto Dave Levin on April 24, 1936.

He also possessed a great eye for young talent, as he was instrumental in launching the career of Buddy Rogers; and he also served as a chief promoter of women's grappling, booking the likes of Mildred Burke and the Fabulous Moolah over several decades.

It was also Pfefer who helped the legendary Sam Muchnick promote his first show in 1945; and in subsequent years, he constantly shifted his base of operations, running territories in Toledo, Nashville, Boston, and on the West Coast while solidifying his place among the industry's top marketers.

However, while working as an agent for promoter Fred Kohler in the 1960s, Pfefer was largely blamed for ruining the Chicago territory when he booked a number of sound-alike performers like “Bummy Rogers”, “Hobo Brazil,” and "Bruno Sanmartino", thus repelling most of the industry's top-flight talent.
