Lacaille
Abbé Nicholas Louis de la Caille, 1713--1762)

Lacaille compiled a catalog of 42 nebulous objects, of which 8 are non-existent though (although Vehrenberg gives a NGC number for one of them). Lacaille classified his objects in 3 categories:
  1. Lac I Nebulae
  2. Lac II Nebulous Star Clusters
  3. Lac III Nebulous Stars
However, though this classification may have been suggestive with Lacaille's very small instruments, it does not correspond to actual properties of the objects (perhaps besides that all existing category II objects are actually open clusters, with or without nebulosity).

This catalog was compiled during his 2-year journey to the Cape of Good Hope in 1751-52

The Lacaille catalog has been originally published under the title "Sur les etoiles nebuleuses du ciel Austral" (On the Nebulous Stars of the Southern Sky) in the Memoirs of the Royal Academy of Sciences in Paris, 1755, and reprinted together with Messier's catalog in the "Connaissance des Temps", both with the second version in 1780 (for 1783) and the final version in the "Connaissance des Temps" for 1784 (published 1781).
