Dunn plied his trade while professional at Westward Ho! from 1886–88 before traveling to Biarritz, France, where he instructed wealthy patrons on the fine art of swinging a golf club. It was in Biarritz where Dunn first made the acquaintance of the American millionaire William K. Vanderbilt. After arriving in the United States in 1893—a trip that was sponsored by Vanderbilt—Dunn spent the summer giving golf lessons at the Newport Golf Club in Rhode Island. After spending the winter back in his regular position at Biarritz, he made a return voyage to America. Golf was beginning to gain in popularity at this time and Dunn found ripe pickings in golf-related work and settled in the U.S. permanently. His first professional position was at the Ardsley Country Club, Ardsley, New York, where he designed the course and settled down to a club-making business in 1896. He was joined by his nephew, John Duncan Dunn, who emigrated from England where he had been engaged with the firm of Dunn Brothers. The clubs the Dunns produced provided an interesting mix of traditional Scottish values and modern ingenuity. Early clubs from the Ardsley days were imported from Scotland and assembled in New York. Some of these irons bear a small eagle mark, a reference to his new home and were possibly forged by Robert Condie. Others were simply marked "Dunn Selected" in either script or block letters and dated from 1897–1903.
Patents and golf club designs
One of Willie's first American patents was his "indestructible driver". Its head was a wood block encased in an aluminium shell, the wood being exposed at the face and on top. In the early 1900s, Willie experimented with plastic-like substances, finally patenting several types of drivers and putters. The substance was known as pyralin and came in black and white versions. Clubs included standard drivers, duplex drivers and mallet putters and for manufacturing purposes the patents were assigned to the Kempshall Manufacturing Co. in Arlington, New Jersey.
