In existographies, Julius Robert Mayer (141-77 BE) (1814-1878 ACM) (IQ:180|#176) (ID:2.86|63) (Becker 160:119) (HGC:254) (CR:94) (LH:7) (TL:101|#119), aka “Mayer of Heilbronn” (Tyndall, 1863), pronounced: "My-Your"[1], was a German physician and physicist, noted for his 1840 discernment on the mechanical equivalent of heat.

Overview

In 1840, Mayer, working as a physician aboard a Dutch merchantman ship destined for a roundtrip to Java, noticed that the ocean water was "warmer" during a storm, which led him to deduce that water can be "heated" by mechanical means, a principle that eventually came to be defined as the mechanical equivalent of heat.

The following are quotes on Mayer:

“Thirty-four years ago [1829], Mayer, of Heilbronn, with that ‘power of genius’ which breaths large meanings into scanty facts, pointed out that the blood was the ‘oil of the lamp of life’, the combustion of which sustains muscular action.”
John Tyndall (1863), “Vitality” (pg. 96) [2]
