In August, 1850, the Reverend Samuel Parker brought a paper to the American Association for the Advancement of Science Meeting. The paper purported to describe a terrestrial snail species that was new to science.
The result was sort of a smack down from the most influential scientist of the day, Professor Louis Agassiz.
Here is a photograph of Prof. Agassiz.
As you may remember, Samuel Parker was the father of Henry W. Parker, and the future father-in-law of Helen Parker.
