Thank you. I never took the time to look up the women in the picture.
Diamond used to be involved in Hollywood productions and has foundation dealing with AIDS. Annenberg used to be an advisor to Reagan and Bush senior for a brief period of time and was lauded by the Bushes after her death. She also had a foundation (Annenberg Foundation) which is still active. Brooke Astor was the wife of Vincent Astor, the son of Titanic victim John Astor. She used to be heavily involved in charities too.
I can imagine who they schemed behind closed doors to create crisis and diseases (e.g., AIDS) in the first place, just to offer a cure and engage in (venture-)philanthropy afterwards.
