Was Frederick Law Olmsted a freemason?

Answer 1

Unless the person specifically states that he is a member of the Freemasons, it is hard to know for sure.

That being said, Frederick Law Olmsted was most likely never a Freemason. He is not listed in William R. Denslow's definitive work, 10,000 Famous Freemasons, or by any other reputable source. Understand that, in most cases, it is virtually impossible to prove a negative, therefore one cannot say with absolute certainty that Pasteur was NOT a Freemason, but there is no evidence to indicate that he was.

Masonry, like most groups, is very proud of its famous members and usually points them out, so if evidence existed, Olmsted would be claimed as a member by the Fraternity. When only anti-masons are the ones claiming someone was a Mason, it is very unlikely that the person really was. Despite what some say, Freemasonry simply isn't a "secret society" and there are generally plenty of records to be found.
