Inscription.  Another life-long employee of Lowell Observatory, Henry is best remembered for his Proper Motion Study of 1971, which entailed repeating the Pluto search plates after 25 years to determine whatever changes had taken place in the background of stars. Henry served as Lowell’s Secretary Treasurer for most of his years on Mars Hill.

Henry’s father Eli also worked for Percival Lowell, installing in 1910 the 42” reflector now on display near Steele Visitor Center.
