What they won’t do is avoid the problems associated with air pollution, as suggested in this January 22, 1916 ad for Sturtevant fans and blowers. Not the first time we’ve seen some blowing action, but this is for humans, not musical instruments.
Evidently the company in question, B. F. Sturtevant, was quite the innovator and projector of many improvements in what is now tituled air handling. Per their historic\fan site, it appears the company’s lineage ended definitively in 1989.
Worth noting in the fine print is the claim that they supply all three branches of the federal government: the executive mansion, the halls of Congress and the Supreme Court (which at the time, worked out of the same building as Congress, if WikipediA is to be believed).
I have to recommend the web page, Sturtevant Survivors, for its very broad collection of various products of the firm in various locations (so far away as New Zealand and Russia!) and also its mention of the Antique Fan Collectors Association, which I did not know existed.
