Rumford in 1798.
Details
A bore was fitted into a stationary cylinder and pressed
against the bottom by a screw. The bore was turned by a team of horses
for 30 minutes, after which Lord Rumford ``suffered the thermometer to
remain in its place nearly three quarters of an hour, observing and noting
down, at small intervals of time, the temperature indicated by it''.
