15742 Laurabassi           Discovered 1991 June 6 by E. W. Elst at the European Southern Observatory.
Laura Bassi (1711-1778) was the first woman to receive a philosophical degree in physics at a European university (Bologna). Not allowed to teach, she gave lectures on physics and performed experimental demonstrations, based on Newton's Principia, at her home. Name suggested by K. Leterme.
