The anonymous donor was Colonel John Weir who lived at Ingleholm in Clifford Road, North Berwick and was conferred Honorary Life Member in 1909. Colonel Weir, although a United States citizen and of Mexico, was born in Scotland in 1852. He made his fortune in America and was president of the Nevada-Utah Mines & Smelters Corporation. On 14th April 1912, Weir perished in the Titanic disaster and his body was never recovered. The former coachman from Innerleithen is remembered annually when the Glen Ladies compete for the Colonel Weir Rosebowl.

George Duncan who won the professional tournament was later appointed head pro at Wentworth and was Open Champion in 1920. He was hired by Edward Esmond, a wealthy financier and race horse trainer who owned a summer house in North Berwick, to travel to Paris for a month each autumn and coach his daughters to play golf. In 1925 Esmond presented a trophy to be competed among the artisan golfers in East Lothian. The Esmond Trophy was first played over the Glen golf course (1925-1945) before being moved to the West Links until the present day.

D & W Auchterlonie, from the famous St Andrews club making family opened a workshop on the Glen course in 1907. David was the clubmaker while Willie Auchterlonie, the 1893 Open Champion gave lessons. Clubs stamped with Auchterlonie - North Berwick are highly collectable. An iron putter made by Willie Auchterlonie at North Berwick circa 1910 is on display in the British Golf Museum. In 1907, Tommy Hume was also a pro golfer at the Glen, working on his own account while living with his family in the Rhodes Farm Cottages. Alex Marshall, the clubmaker at 27 Station Hill took over Auchterlonie's workshop in 1911 where he repaired clubs. He was followed in 1919 by Robert Thomson who was appointed Burgh golf professional from 1923-1938.

In the Open Championship he finished in the top six in 1903 and 1905 and was Scottish Professional Champion in 1909 after defeating Willie Watt from Dirleton in the final. He replaced James Braid at Romford Golf Club in 1904 and three years later returned to North Berwick. He regularily played in the prestigious News Of The World tournament at Sunningdale and received £10 prize money in 1912. Robert Thomson remained single and died in 1954 aged 78 years.

In June 1914 the Scottish Professional Championship was played over the Glen golf course. David Watt from Dirleton scored 71 in the fourth round to oust his brother Willie Watt from the leadership which he held from the start. David won by a couple of strokes and became the first left-handed player to win a professional tournament. David Watt apprenticed as a clubmaker with Andrew Bissett at North Berwick before being appointed golf professional at Mortonhall. Three years later David Watt died of wounds suffered during WW1 while fighting with the Gordon Highlanders at Arras in France.

Tom Dickson from North Berwick was appointed professional and clubmaster at the Glen Golf Club in 1935. Following WW2 the Town Council appointed Arthur Fennell (1910-1974) as professional. He leased the timber building beside the first tee where he sold clubs and balls and arranged golf lessons. He also had a sports equipment shop at 27, Quality Street, North Berwick.
