A. Tillinghast

Albert Warren "Tillie" Tillinghast (1876–1942) stands as one of golf's most prolific architects, having worked on more than 265 courses during his career. Inducted into the World Golf Hall of Fame in 2015, Tillinghast was a central figure in the "Philadelphia School" of golf course architecture, a group that collectively designed over 300 courses and shaped American golf during the sport's formative decades.

Tillinghast's work is characterized by strategic design principles that have stood the test of time. Among his designs featured in Course Vaults is Rockaway Hunting Club in Lawrence, New York, which exemplifies his thoughtful approach to routing and green complexes. His portfolio includes numerous courses that remain highly regarded by golfers and critics alike, many of which continue to host competitive championships nearly a century after their creation.

His influence on American golf architecture remains substantial, with many of his courses still considered benchmarks of classic design.
