I did some searching, and I believe the credit should go to the Englishman Sir Thomas Clifford Allbutt .......befitting last name. He invented the first practical clinical thermometer in 1867, which was only 6" long. Previous thermometers were nearly a foot long, and could take as long as 25 minutes for an accurate oral reading. So, just a guess, but the first real rectal temperature probably happened in Old Blighty sometime around the 1860s.

TY, I would like to see the foot long rectal thermometer. Could stick up a butt for 25 minutes.
