1893 Melbourne, Politics: Archduke Franz Ferdinand of the Austro-Hungarian Empire arrived in Melbourne for a tour that included hunting parties and barbeques. He continued on around the world. His murder later would spark World War I in which millions died including thousands of Australians. Below is an image of his bloodied jacket.

1902 Antikythera Island, Archaeology: Spyridon Stais found the Antikythera mechanism in a shipwreck off the eponymous Greek island. It is a clockwork mechanism from 205 BC with a gear, perhaps to model the movement of objects in the sky.

1954 Topeka (Kansas), Law: The Supreme Court held that segregation violated the Fourteenth Amendment of the Constitution in (Linda) Brown V the Board of Education. Note that the leader of this unanimous decision was Republican Chief Justice Earl Warren. The grade school in question is now a Civil Rights museum which I have visited a couple of times. It has some bloodcurdling displays of racial hatred.

The raft (pictured below) was called Ra II and crossed four thousand miles of ocean in fifty-seven days to reach Barbados.
