For a long time I saw a title in the list of movie crew positions that was strange to me, ***Best boy***. 

[Wikipedia](https://en.wikipedia.org/wiki/Best_boy) says about that: 

> 
> In a film crew there are two kinds of best boy: best boy electric and best boy grip. They are assistants to their department heads, the gaffer and the key grip, respectively. In short, ***the best boy acts as the foreman for his/her department***.
> 
> 
> 

I could not find a clear connection between the title and its role. So, what's the origin of this title and position?
