Howard Head. Howard Head (July 31, 1914, in Philadelphia, Pennsylvania – March 3, 1991) was an American aeronautical engineer who is credited with the invention of the first commercially successful aluminum laminate skis and the oversized tennis racket. Head founded the ski (and later tennis racquet)-making firm, Head, in 1950. Later, he became chairman of Prince Manufacturing Inc. The U.S. patents for the laminate skis and oversized tennis racket are in the name of Howard Head. He graduated from Harvard College in 1936.

Ski equipment 

In 1947, Howard Head was an aircraft engineer for Glenn L. Martin Company in Baltimore, and went skiing for the first time. Head was frustrated with the quality of the wooden skis, which he found clumsy and heavy and felt they made skiing very difficult for beginners. He decided to develop a lighter and more efficient ski that could make skiing much easier for all users. He left his job and devoted all his time and energy to developing the skis and supported himself with earnings from poker.

The skis developed by Head were based on the structural principles that he had learned during his experience as an aircraft engineer. In a warehouse he rented from Albert Gunther Inc in an alley off of Biddle Street in downtown Baltimore, he used a technique known as metal sandwich construction. The first skis he made consisted of two light layers of aluminum bonded to sidewalls of thin plywood, with a center filling of honeycomb plastic.  Although these skis were very light, they all broke quite quickly during trials.  Head did not give up on his idea, and was encouraged by several professional skiers, including 1939 World Champion Emile Allais and ski instructors Clif Taylor and Neil Robinson, who assured Head that he would love to use his skis if they did not break.  Throughout that winter Head would make a ski pair and send it out to Robinson, who returned it to Head after it broke.  Head figured out the flaws of his design, came up with modifications, sent the new ski pair to Robinson, and the process repeated. By the end of the winter of 1947, Head came up with skis that were as strong as wooden skis but were half the weight.

In order to make his skis more efficient, Head made several other changes, like substituting plywood for honeycomb plastic, covering the bottom of the ski with polyethylene to avoid the problem of icy bottoms and adopting continuous steel edges to harden the edges of the ski.  The new improved skis were almost as heavy as the conventional wooden skis, but were stronger and easier to control.  Head skis helped to popularize alpine skiing in the U.S.; the innovative equipment made turning significantly easier.

In 1950, Head founded the Head Ski Company, which became very successful.  Within a couple of years it was the major supplier of alpine skis in the U.S. and influenced ski design worldwide. The company later diversified into tennis and other racquet sports; its most notable product was the innovative Arthur Ashe racquet, constructed of aluminum honeycomb. Howard Head sold the company to AMF in 1969 and retired.  After a number of takeovers and acquisitions, HEAD, N.V. is currently based in Kennelbach, Austria (operational) and Amsterdam, Netherlands (corporate offices).

Tennis racquet 
After retiring, Head decided to take tennis lessons. For this purpose, he purchased a tennis ball machine manufactured by Prince Manufacturing Inc.  Not particularly proficent at tennis, Howard felt that the equipment for the game needed improvement. He became the majority shareholder and chairman of the board of Prince through an acquisition. While Head considerably improved the design of the ball machine, he still did not get any better at the game. He believed that a big factor that was slowing his improvement was the small 'sweet spot' of the tennis racquet. In order to make the game of tennis easier, Head came up with the design for an oversized racquet.  He filed and obtained a patent that covered tennis racquets with a size of 95–135 square inches. He also pioneered the development of the graphite racquet, which eventually became the industry standard, replacing wooden racquets.

Although Prince was the first company to patent oversize racquets, the Bentley Fortissimo preceded the patent by two years, causing Germany to invalidate it. Weed also introduced an oversize racquet in 1975, before the first Prince oversize, the aluminum Prince Classic, was introduced.
