RT @NobelPrize: Today we celebrate the bravery and achievements of Werner Forssmann, born #OTD, who put his life at risk by performing the first human heart catheterisation - on himself. The experiment in 1929 paved the way for many types of heart studies and led to a #NobelPrize.

Radosław Sikorski (po) retweeted @AJC_CE :

RT @AJC_CE: #OTD in 1943 Jewish prisoners of the death camp at #Treblinka launched a revolt attacking German and Ukrainian guards. 300 inmates escaped, but only 100 survived the massive SS manhunt. We honor the courage of those who rebelled and remember the 800K who were murdered. #Zakhor!

Americans voted leave #OTD 1776. Things seem to have worked out OK for them. Happy #IndependenceDay, cousins.
