		| Abstract: | In 1900 Lowell Observatory assistant Andrew Douglass advised his
 employer Percival Lowell to purchase a state-of-the-art spectrograph from instrument\newline
 maker John Brashear of Pennsylvania.  Lowell agreed with Douglass's
 suggestion, realizing that such an instrument was critical for the Observatory
 staff's research.  However, the purchase also fulfilled a little-known
 obligation between Percival Lowell and Brashear that dated back to an accident
 occurring in 1895.  If not for this unusual incident that led to the purchase
 of the spectrograph, the future of Lowell Observatory and, on a larger scale,
 unmasking of the nature of the expanding universe, would likely have played out
 much differently. |
