Summary

Description
English: This is a cropped copy of an engraving of physicist John Tyndall (1820-1893). At the foot of the uncropped copy is the words: "Etch by H.B. Hall N.Y. 1878". Tyndall would've been 58 in 1878 but looks younger than 58 in the engraving. The engraving was done from a photograph dated some years earlier (perhaps 1872 because Tyndall was in New York (N.Y.) in 1872).
