October 24, a date as any other? (and Stamps of the Day)

There is probably some significance to each date during a year, but somehow this date is stuck in my mind.  Maybe because my oldest grandparent was born on this day in 1897 and that seemed so far, far away in time, even when I grew up many decades ago.  So, I had to look up what else had happened on this date. Very many things indeed - telegraphs, stock crashes and so on.  

Here are some things listed on Wikipedia:

1632 – Anton van Leeuwenhoek, Dutch microbiologist was born (d. 1723) (Imagine seeing cells and moving euglenas for the first time, in the water you drink... )

1861 – The First Transcontinental Telegraph line across the United States is completed, spelling the end for the 18-month-old Pony Express. (From horses to copper lines. )

1929 – "Black Thursday" stock market crash on the New York Stock Exchange. (A big stock market crash also happened on Oct 24 2008)

 1931 – The George Washington Bridge opens to public traffic. (It now costs $12 to cross it into New York City)

 1945 – Founding of the United Nations (I didn't know they had their own stamps)
