Just a note on Strouse. In around 1915 Tillinghast reported that Philmont South was a nice course, but had no artificial bunkers and clearly needed some, and the men in charge of PHilmont, Ellis Gimbel, etc., saw what "experts" like Wilson, Crump, Smith, Klauder, et.al. had done at Cobb's Creek and were greatly impressed.
By 1917, a Philadelphia Inquirer article by "Billy Bunker" talking about who in Philadelphia might be affected by a recent decision on amateurism of architects wrote;
"Many of the golf courses here were built in the old days when the architect was practically unknown. In recent years, many of these courses have been remodeled. The Philadelphia Country Club was changed and greatly improved by Walter Travis, one of the many amateurs who have been affected by the new ruling which bars as amateurs men who "construct" (my emphasis for a term of the time indicating and including "design) golf courses. A.W. Tillinghast, a Philadelphian, who intends to keep on with his golf course construction work, remodeled both the St. Davids and the Old York Road Country Clubs."
"Both of the Merion Cricket Club courses were built under the direction of Hugh Wilson who also laid out the Seaview course. Philmont is largely the work of Henry Strouse and Hugh Wilson. Aronimink has had many architects including George Klauder..."
