Whatever name you want to use, World Animal Day or Animal Day, it doesn’t matter. You know it’s about 4 October. The day in the calendar that equals the day when we pay extra attention to animals worldwide. Not a year goes by without this day passing by.

Florence and Berlin
That doesn’t get us there yet. The only question is what exactly was the place where it began? Was it Florence or Berlin? If you assume it was Hermann Zimmermann who created the first truly international version of World Animal Day, it was in Berlin. It was on October 4, 1925, at the Sport Palast. This was to take place at a gathering of more than 5,000 people. He linked this to the day centred on St Francis of Assisi. There was just one problem, this event ended up not going ahead. The event was rescheduled for October 4, 1929. Nevertheless, Zimmerman continued to do his best to raise awareness of World Animal Day after 1925.
