Today in history there were 2 odd weather occurrences in the world. In Sydney, Australia there was a record heat day -hottest day in 80 years of 47.3 degrees Celsius (117.14 degrees Fahrenheit). On the other end of the world snow fell (15 inches) in the Sahara Desert in Ain Sefra in northwest Algeria. Hell freezing over and such.
There were patents for the typewriter (1714) and the fountain pen (1890) and Galileo discovered the first three moons of Jupiter (1610). Fire destroyed Jamestown in 1608, five years after its founding. five duly elected Socialist assemblymen were denied by the New York State Assembly (part of the first Red Scare) in 1920, and in 1959 the US recognized the Cuban government of Fidel Castro (that would change quickly).
As far as significant birthdays: Pope Gregory XIII, who introduced the Gregorian calendar (the one we use today) was born in 1572. Millard Fillmore, 13th US President (forgettable) was born in 1800. And in 1971 actor Jeremy Renner, currently recovering from a snow plow accident was born.
