Dr. Joshua Frost’s Calculation of an Eclipse

While exploring the fictionalized account of the early military career of Jacob Frost, I mentioned his younger brother, Dr. Joshua Frost.

Dr. Frost graduated from Harvard College in 1793. The university still holds his drawing of the lunar eclipse that would occur on 14 Feb 1794. Massachusetts was on the edge of the viewing area while states outside of New England got no sight of this eclipse.

Thus, even though David Rittenhouse was making astronomical observations in Philadelphia that year, he had nothing to observe.
