David Attenborough, 92 – $35 million
When we think of natural history documentaries, the name of Sir David Attenborough is the first that comes to mind. The man who has been referred to as a national treasure in Britain is the only person to win a BAFTA for programs in black and white, color, HD, 3D, 4K. David wrote and presented nine documentary series about animal and plant life from the Life series. If he ever needs it, the 92-year-old Attenborough can afford whatever elder care he wants with his $35-million fortune. Many species have been named by him, including most recently, a species of phytoplankton, in 2018.
