In May, Basel commemorates several significant historical events. Emilie Louise Frey began her studies at the University of Basel's medical faculty in 1869, becoming the first female student there and later the city's second female doctor. More information on her can be found at this link. In 1856, one of the last cantonal professional armies in Switzerland was dissolved, a decision influenced by the Neuenburgerkrise, which threatened Basel with a potential occupation. Details are available here. The Basel Central Station was inaugurated on June 4, 1860, replacing an earlier station and later succeeded by the current station in 1907. Additionally, on June 7, 1879, the Wettstein Bridge was opened, marking it as the third bridge in Basel and the first modern one for general traffic.

The following tables present notable Basel personalities whose birth or death anniversaries fall in the current month, along with a selection of events that are upcoming or ongoing.
