October 18th appears to be national possession day, as that was the day the United States took possession of Alaska (1867) and Puerto Rico (1898), and musician Paul Kantner took possession of marijuana in Hawaiʻi (1969), who was only following in the footsteps of John Lennon and Yoko Ono, who one year earlier discovered marijuana in their flat (1968).
Happy birthday to:
Chuck Berry (1926)
Terry McMillan (1951)
Wynton Marsalis (1961)
Sorry to see you go:
Charles Babbage (mathematican Dec 26, 1791 -- Oct 18, 1871)
Thomas Edison (inventor Feb 11, 1847 -- Oct 18, 1931)
