In case this piqued your interest, I really enjoyed the documentary about his life's journey, https://en.wikipedia.org/wiki/Oliver_Sacks%3A_His_Own_Life - can recommend! (Also, fan of his books and research.)

I second the documentary.

Also a very notable statistic/anecdote at the end. I don't know how wide the scope (only one university?), but about a third of the incoming neurology students chose the field because of Oliver Sacks.

I always found the bulk of the criticism leveled against him to be faulty. However, if he did indeed fabricate a lot of details - it is concerning.
