Harold Edward Swash (3 February 1933 – 8 December 2016) was an English golf coach, putter designer and inventor. Known as the "Putting Doctor", Swash was one of Britain's best-known putting specialists and worked with numerous professional golfers, including Nick Faldo, Pádraig Harrington, Darren Clarke and Lee Westwood. He developed and popularised a number of innovations in putter design, including face-balanced putters and associated shaft and hosel configurations, long putters and grooved-face technology later commercialised as the C-Groove putter.

Early life and career

Swash was born on 3 February 1933. He played football to a high standard, including for Aston Villa F.C.'s reserve team. After suffering a broken leg, his rehabilitation led him to develop a particular interest in golf's short game and putting.

Swash had a professional background in engineering and applied engineering principles to golf equipment and putting technique. He was based in Southport, Merseyside, and was a long-time member of Hillside Golf Club.

Putter design and inventions

Swash designed his first putter in the early 1960s and subsequently developed a career combining engineering, equipment design and putting instruction.

Although the general principle of face balancing in putters pre-dated Swash, he was an important developer and populariser of face-balanced putter designs and the shaft and hosel configurations used to achieve them. His work formed part of the development of commercially available putters designed to reduce the tendency of the club face to rotate during the stroke. His engineering approach to putter design was associated with the development of the Fazer "No Twist" range and other putter designs.

Swash was also an early designer of long putters. In 1989, he introduced Royal and Ancient Golf Club of St Andrews secretary Michael Bonallack to the broomhandle style of putter. Swash told The Independent that he had shown Bonallack a prototype putter he was making for Sam Torrance. Torrance subsequently became one of the most successful professional users of the long putter, with contemporary reporting describing his career as having been transformed by its use.

Swash's most notable equipment invention was the grooved putter face. He developed a system of concentric grooves designed to influence the way the ball left the putter face and to promote forward roll. The design became known as the C-Groove putter.

In United States Patent No. 5,637,044, Golf clubs, Swash is identified as the inventor of a putter incorporating multiple grooves in the ball-striking face. The patent has a priority date of 14 October 1994 and was granted on 10 June 1997.

Swash's C-Groove technology subsequently became associated with professional golfers including Retief Goosen. Writing in 2004, The Independent described Swash as the "granddaddy of British putter designers" and the inventor of the C-Groove pattern, noting that Goosen had won two U.S. Opens using a Swashbuckler putter.

Coaching

Swash became widely known as the "Putting Doctor" and coached numerous leading professional golfers. His pupils included Nick Faldo, Pádraig Harrington, Darren Clarke and Lee Westwood.

Swash worked with Darren Clarke during the 1990s, with contemporary reporting describing him as Clarke's putting mentor. Clarke subsequently continued to work on his putting with Swash and credited changes to his putting technique with helping his performance.

Swash also worked with Colin Montgomerie on his putting during Montgomerie's career.

His coaching relationship with Pádraig Harrington also formed part of his work with leading European professionals.

Harold Swash Putting School of Excellence

Swash established the Harold Swash Putting School of Excellence, which became an important centre for putting instruction and the development of putting coaches.

One of the coaches associated with the school was Phil Kenyon, who worked alongside Swash and subsequently became a leading professional putting coach. The school continued after Swash's death as part of the coaching legacy established under his name.

1998 Masters medical emergency

At the 1998 Masters Tournament, Swash suffered a ruptured aortic aneurysm after collapsing while being taken to the medical centre. He survived the medical emergency and subsequently returned to Augusta National Golf Club for several years to meet and have dinner with people who had helped save his life.

Death and legacy

Swash died in hospital on 8 December 2016, aged 83. His death was followed by tributes from golfers, coaches and figures within the golf industry.

His legacy encompasses both golf instruction and equipment design. His work on putter design included the development and popularisation of face-balanced and long-putter configurations and the patented C-Groove grooved-face technology. His approach combined engineering principles with practical putting instruction and influenced subsequent generations of golf equipment designers and coaches.
