Yes, Nelson Mandela was a very big deal. The death today of the anti-apartheid activist, political prisoner and former president of South Africa touched the lives of millions. Celebrities too, several of whom had met the man, were united in their praise of Mandela, paying tribute though Twitter.

I join the people of South Africa and the world in honoring the life of Nelson Mandela. His commitment to freedom and equality and his dignity will be remembered forever throughout the world.
