| 9130 Galois | Discovered 1998 Apr. 25 by E. W. Elst at the European Southern Observatory. |
| Named in memory of the famous French mathematician Evariste Galois (1811-1832), well known for his contributions to group theory. At the age of only 16, he launched himself into a deeper understanding of the essential conditions that an equation must satisfy to be solvable by radicals (Galois theory). He died in Paris in a duel, under circumstances that have never been fully explained, although his republican activities and sympathies were well known. |
