After reading all the posts I felt, for me, the single event that rippled through out the world and its repercussions are still being felt today (and will be in the future) was the attack on the World Trade Center in New York, 9/11.
I'm so glad you mentioned this. When birth control pills became widely available, and I began taking them, I asked a lot of older women what they thought of this invention. The opinions ranged from wishing they had had those little pills to wishing they hadn't been married because they didn't want children. One woman in her late eighties said she loved her husband, but loving him so much produced children she didn't want. The stress resulted in less love, and then no love. She couldn't imagine having lots of sex and no babies. I think birth control pills are right up there with the printing press. Thank you so much for your answer.
The freedom to choose whether to have children, when to have children and how many to have, allowed women to more easily pursue an education, compete in the workplace and rise out of poverty.

A benefactor to women and families everywhere. But in mentioning Djerassi we should also remember Rutherford and penicillin. Thanks for an original nomination, Jane. This question has attracted some brilliant answers.
Posting questions is interesting because you never know which ones will be successful and which will die an early death. The few that run to three pages of responses, as this one did, are well worth while.
Lamarr and Antheil realized that radio-controlled torpedoes, which could be important in the naval war, could easily be jammed, thereby causing the torpedo to go off course.[18] With the knowledge she had gained about torpedoes from her first husband, and using a method similar to the way piano rolls work, they designed a frequency-hopping system that would continually change the radio signals sent to the torpedo.[19]
Their invention was granted a patent on 11 August 1942 (filed using her married name Hedy Kiesler Markey).[20] Yet, it was technologically difficult to implement, and at that time the U.S. Navy was not receptive to considering inventions coming from outside the military.[16] Only in 1962 (at the time of the Cuban missile crisis) did an updated version of their design appear on Navy ships.[21] The design is one of the important elements behind today's spread-spectrum communication technology, such as modern CDMA, Wi-Fi networks, and Bluetooth technology. https://en.wikipedia.org/wiki/Hedy_Lamarr

Beans, that is staggering on so many levels. First that Lamarr had that capability, second that the USN refused to take advantage of it, third that it was found useful on still another level. I appreciate this answer.
World war 1. Supposedly the war to end all wars. Little do most understand it is the event that marked the beginning of the end of this system of things. (Matthew 24:3-8; revelation 6: 2-8; 12:9-12)
