Sergey Brin
During Burning Man Festival of 1998, Larry Page and Sergey Brin designed the first doodle in order to notify users of their absence. Subsequently, Dennis Hwang was assigned to create Google logos. Hwang's first logo design for Google was in honor of Bastille Day, July 14, 2000, at the request of Larry Page and Sergey Brin, and he has been designing the specialty logos ever since. He creates about 50 Google logos each year. Other logos have been designed commemorating Thanksgiving, Christmas, and other events such as Piet Mondrian's birthday. Hwang also designed the iconic Gmail logo on the night before its release.
