Update: Please see the comments for corrections about this post.
A relative of Hulett C. Merritt emailed me after I posted about the Merrit Mansion last week. He was kind enough to send me clippings of obituaries and some lovely old post cards. Above, the sunken garden. Below, as it appears today.
To quote Mr. Merritt's relative:
"I was in Pasadena for a week in December 2008, the first time I had been back in nearly 25 years. I walked around both Hulett's mansion as well as Lewis' mansion [the nearby Tudor]. My great grandparents used to come out from the Midwest to spend the winter months in Pasadena back in the 1930s. To some degree, I found that parts of Pasadena still have that slow pace of life that attracted snow birds in previous times."
(If I've got it straight, Lewis was Hulett's father.)
The gentleman sent me even more great information which I'll save for another time. Perhaps we'll do a post about Lewis' mansion one of these days.
