Today is the 95th birthday of Nelson Mandela, former President of South Africa and 1993 Nobel Peace Prize winner, to name just a couple titles. Even the United Nations General Assembly proclaimed Mandela's birthday, 18 July, as "Mandela Day". So why no Google logo for Nelson Mandela today, while he sits in his hospital bed possibly on his last days?
There have been random complaints about the lack of a logo in the Google Web Search Help forums.
Truth is, Google has never had a logo for a living person before. They have done so for "things" but not for living people, as far as I know. At least, it is not the norm for Google to honor a person who is still living.
I am sure that when the time comes and when Nelson Mandela passes, Google will make sure to honor his memory with a respectful and symbolic Google Doodle.
For now, let the man live and be well.
Happy Birthday Nelson Mandela.
