What was Alister MacKenzie up to in the 1930s? For one thing, he was building Augusta National. But more generally, MacKenzie was exploring new forms of golf architecture and producing some genuinely experimental, even radical, courses. In this episode, Garrett Morrison speaks with Josh Pettit, founder of the Alister MacKenzie Institute, about MacKenzie’s wild ’30s: what projects he completed, how this era of his career influenced the design of Augusta National, and how it might light the way forward for golf architecture in the 21st century.
