Mercer Automobile Company was founded in 1909 at Trenton, Mercer County, New Jersey by a handful members of the prominent Roebling and Kuser families. Ferdinand Roebling, son of John A. Roebling, famous designer of the Brooklyn Bridge, was the president, and his nephew Washington A. Roebling II was the general manager. The secretary-treasurer was John L. Kuser, who, with his brothers Frederick and Anthony, had amassed a fortune from banking, bottling and brewing. The founders’ focus on the competition resulted in 35R Raceabout racing car. Its inline 4-cylinder T-head engine displaced 293 cubic inches (4,800 cc) and delivered 58 hp at 1700 rpm, in racing trim 85 hp at 2500 rpm. The Mercer Raceabout raced at various AAA events in 1910-1912 seasons. In November 1910 29-years old Washington Roebling appeared at the wheel of the Mercer racer in Savannah Trophy Race. It was 231-300 ci Car Class Race, sanctioned by AAA, one of the events preceded the American Grand Prize. Roebling finished 2nd behind Joe Dawson in Marmon.
