Dick Porter, of Onset MA, has been building his collection of over 5000 thermometers since the mid-80s, though the collection has nearly doubled since 1998 when it was just over 3000. He calls it the world’s largest and only thermometer museum. He’s certainly passionate about them, and he’s been an invited speaker at more than a few thermometer and weather related events, like the christening of the world’s largest thermometer in Baker California.
The collection, which Porter values at about $4 per piece, fills his home’s small basement, and visitors should expect him to be an active docent. He has stories about many of the thermometers, even some memories of the day the scientific community decided to honor Anders Celsius by eponymously renaming his centigrade scale. Thinking of scales, Porter even has a few Reamur thermometers. Impressive, yes, though Wikipedia notes a few more temperature scales he didn’t mention. I guess it’s challenges like that that get a guy through the day.
It’s all at 49 Zarahemla Road Onset, MA 02558, and visitors should probably give Mr. Porter a call (508) 295-5504 to confirm he’ll be home to host you. All info current as of my October 2005 visit, more info at Roadside America and Odd New England.
