During that Open, James Braid was the first player to break 70 when he scored 69 in the third round. However Jack White matched that in the final round to win by one stroke. Braid had to settle for a share of second place with J.H. Taylor, who in the fourth round established a new championship record 68. White received the gold medal and 50 pounds in prize money.

With the national championship's of America and Great Britain in the hands of North Berwick men, this was a golden era for the town with a population of only 2,200. Unfortunately the battle to be 'world champion golfer' did not materialise as Jack White suffered from ill health and could not make the journey. The Sydney Morning Herald in Australia reported that Jack returned to North Berwick to convalesce and visit his parents. His only exercise was confined to playing bowls on the North Berwick green.

In 1905, White was amongst a group of professionals including Willie Anderson, Sandy Herd, Andrew Kirkaldy, Rowland Jones and Tom Vardon who were invited to San Pedro de Los Pinos in Mexico to play a series of exhibition matches. The President of the Mexican Country Club wanted to promote winter golf in the region, and attract the American's over the border. It was reported in the New York Times that money prizes were offered to the four foreign celebrities to induce them to make the arduous trip to Mexico.

In December 1905, Jack White sailed the Atlantic from Liverpool on the steamer S.S. Carmania with Ben Nicholls (New York G.C), Alex Herd (Huddersfield) and Rowland Jones (Wimbledon Park). They arrived in New York on 8th January 1906 and took a special train journey to Mexico. The event was played over the San Pedro de los Pinos links in the suburbs of the city of Mexico and was won by Willie Smith with Willie Anderson second and Alex Herd third. In February 1906, when the group returned to the USA a number of the British pro's stayed over to play Pinehurst and Palm Beach. Jack White was not well enough to play in any of the matches in Mexico City and was accompanied back to Scotland by Willie Anderson.

During Jack White's time at Sunningdale his most famous customer was Bobby Jones. Jack assisted Jones, the American amateur to win the British Open championship in 1926. Jones was dissatisfied with his driving and White designed a club with a deep face and with lead arranged to impart over spin, lower flight and longer run. It was at Sunningdale that Bobby Jones shot 66 in the qualifying round for the Open Championship which he described as the 'greatest round of golf ever played', Jones had 33 shots and 33 putts. The Prince of Wales, who White frequently instructed, obtained a similar driver. Sunningdale was also the venue for the News of the World Match Play tournament from 1903 and the blue ribbon amateur event - the Golf Illustrated Gold Vase from 1910. At this time White employed six club makers.

Jack White was the nephew of Ben Sayers and Davie Grant, and his brother-in-law, Wilfred Thomson was professional at the Hermitage County Club in Virginia. Walter Travis, the first overseas golfer to win the British Amateur Championship in 1904, co-authored a book with Jack on ' the game within a game' called The Art of Putting. Australian born Walter Travis won the British title using a centre-shafted putter, which was subsequently banned for many years. He also won the U.S. Amateur Championship three times, and was a contemporary of Dorothy Campbell from North Berwick.

At the start of WW1 Jack White enlisted as a private in the London Scottish regiment. His wife continued the business with two young lads helping. Jack had eight club makers, six were conscripted into the army and two went to Woolwich Arsenal.

Norman Hunter, the well known Cambridge University amateur golfer was captain of Sunningdale G.C. at this time. Hunter was a familiar figure at North Berwick playing with Freddie Tait and Harold Hilton. Norman Hunter enlisted in WW1 and was killed at Ypres on 16th June 1915, aged 36 years. He was a Lieutenant in the Royal Warwickshire Regiment.

Maurice Bowyer, a former apprentice at Sunningdale, later said Jack White was sacked in 1926 for 'drinking and womanising' and almost immediately after that event he formed the Jack White Golf Co. and returned to Gullane were he started a clubmaking business in the property next to the present professionals shop and later in a two storey building (now demolished) in Goose Green Mews. His first apprentice was W. J. 'Bud' Russell, son of Sandie Russell, the starter at Gullane No.1 course. Bud Russell emigrated to Australia in 1930 and was appointed pro at Barwon Heads Golf Club, Victoria where he remained for 57 years. Another apprentice, Hugh Watt became professional at Barnton, before being appointed to Gullane Golf Club. White opened a successful golf equipment shop at 2 Rosebery Place and for many years gave evening class lessons on the art of club making which were very popular.

White was making clubs towards the end of the hickory period, but the wood was so poor quality he contacted Hardy Brothers of Alnwick a fishing rod manufacturer who supplied him with split cane which White used for his shafts until metal took over.

In 1928, Jack White asked the Honourable Company for permission to open a professional shop at Muirfield. This was granted, but to avoid conflict with the clubmaster who had previously sold golf balls to the members, White did not pursue the matter. In 1938, he was appointed professional and starter to the newly opened course at Monktonhall (Musselburgh Golf Club). Jack's wife Elizabeth Proudfoot died 9th March 1949 at 30 Mortonhall Terrace, Musselburgh and Jack White followed her to the grave sixteen days later on 24th March 1949.
