On this day

interesting facts

The first free public school opened in Europe.

In 1616, the first non-aristocratic, free public school in Europe opened. Located in Frascati, Italy, it was the brainchild of José de Calasanz, a priest who was passionate about providing education. It was, in fact, his life's work to help educate younger people – and he helped to open education up to people of all financial backgrounds.

Central America

Central America became independent.

In 1821, the Act of Independence of Central America passed. The act consisted of countries such as El Salvador, Honduras and Nicaragua, Costa Rica, and Guatemala declaring their independence from the Spanish Empire. As you’ll see further down in our guide, September 15th really is a big day for national pride and celebration across this area of the globe!

Charles Darwin

Charles Darwin landed at Galapagos!

In 1835, the HMS Beagle arrived at the Galapagos Islands, with Charles Darwin onboard. It was from the Galapagos Islands that Darwin developed his theories on evolution – in part thanks to the incredible turtles living here, as they can endure centuries of old age! People still visit Galapagos to this day – it’s little wonder why the islands proved so popular with Darwin, and so integral to his research.


Penicillin was first discovered.

In 1928, Alexander Fleming, a Scottish bacteriologist, discovered penicillin while studying influenza. To this day, penicillin is still vital in treating all kinds of infections – it is quite literally a life-saver in millions of cases all over the planet. However, some people are allergic to it – and thankfully, there are now other options readily available!

Japan was rocked by a major typhoon.

In 1947, Typhoon Kathleen hit Tone River, Saitama, and the general Tokyo Area. It killed at least 1,930 people in its path and injured around 1,750 more.
