What was Charles Messier's singular, obsessive goal in the 18th century?

Answer

To be the first to discover a comet.

Charles Messier dedicated a significant part of his observational career to scanning the night sky driven by the intense desire to achieve comet discovery. In that historical period, finding a comet was viewed as a rapid path to achieving scientific fame and recognition, serving as a fast track to prestige compared to the slower process of cataloging stationary, deep-sky objects. This pursuit was so central to his motivation that it propelled him through countless nights of observation, making it his primary ambition despite the fact that his enduring fame rests on his catalog of nebulae.
