“While his primary interest was the Blue Lodge, he also was honored in the Scottish Rite by being coronated as a 33* Honorary in October of 1945 for both his service to Freemasonry and the United States.”

Per this site, Scottish rite has 33 degrees and blue lodges have 3:

Reason I thought there were 3 in Scottish rite was my Scottish grandfather was a master mason, having gone through the other 2 degrees, and my father had been in a different lodge system and was a 32nd degree Mason.
