 Bullialdus AKA Ismaël Boullaiu (1605-1694) - Lunar Madness - Boulliau Home Page - Dr Robert A. Hatch
Although Boulliau (Latin: Bullialdus) owned a certain amount of land (a house in Loudun and two in Paris) the lunar parcels named in his honor are somewhat larger than those owned by more powerful contemporaries.
In any case, if you search the Net for the name 'Bullialdus' it consistently appears in reference to parts of the fourth (small) rock from the sun.
All the web references (dozens and dozens) refer to the Bullialdus lunar craters, none to the astronomer who happened to name the moon's second inequality.

 Ismail Bouillaud (Bullialdus, 1605-1694)   (Site not responding. Last check: 2007-11-03)
Ismail Bouillaud (or Boulliau, or latinized Bullialdus) was a French librarian, astronomer and priest, who was born in 1605 in Loudun where he studied, then traveling in Italy, Holland and Germany for buying books.
Because the "nebula" had not been documented by so many famous astronomers, Boulliau suspected that it might been variable, similar to Mira Ceti which he also studied, and attempted to calculate a period of variation - of 333 days, compared to the modern value of 332.
The astronomical community has named a Moon crater to his honor: Bullialdus (20.7S, 22.2W, 60 km diameter, in 1935).

 Messier 31
XXIX, 390 (1716)] About the Year 1661 another of this sort was discovered (if I mistake not) by Bullialdus, in Cingulo Andromedae [in the Girdle of Andromeda].
It was therefore by an oversight, that Halley ascribes the discovery, in 1661, to Bullialdus (Ismaël Boulliaud); who himself mentions its being known as Nebulosa in cingulo Andromedae, and that it had been noticed 150 years before, by an expert though anonymous astronomer.
The tenuity of its boundary offering no definition for exact comparison, has made the several attempts to figure it so conflicting as to mislead.
