What is the real name of Jane Goodall's son, Grub?

Grub, the son of Jane Goodall and photographer Hugo van Lawick, was born Hugo Eric Louis van Lawick. He was born on March 4 1967, the year after his mother received her PhD in animal behavior.

Grub spent his early childhood in Africa where his mother worked at the Gombe Stream Research Centre. As a result, Grub's early education came from his mother who would teach him in the afternoons once she had completed her research for the day. In 1971 Jan Goodall and Hugo van Lawick divorced. As of 2014, Grub can be found in Tanzania living near his mother beside the Indian Ocean.
