Tolkien had a lot of influence from religion, mythology and geography as mentioned [here](https://en.m.wikipedia.org/wiki/J._R._R._Tolkien%27s_influences) to create what seems like an entire literary universe. It's also not uncommon for authors to be influenced by certain people they know or meet. 

**Is there a character(s) in the Tolkien universe who was based on a real-life person (eg. family member, close friend etc)?**
