I have heard members mention Kirtland Cutter as the original designer. Obviously there have been hundreds of changes made since. Here’s what the internet says about him. Nothing about golf. Maybe he designed the clubhouse?
Kirkland Cutter was an American architect known for his contributions to the architectural landscape of the Pacific Northwest during the late 19th and early 20th centuries. He designed various notable buildings, including academic institutions, government structures, and private residences. His work often exhibited a blend of architectural styles, ranging from Beaux-Arts to Renaissance Revival. Cutter played a significant role in shaping the architectural character of cities like Spokane, Washington, and beyond.
