How much of a role do you view Happy Chandler as having in Integration?

[Topnotchsy]

I was wondering how people viewed Happy Chandler's role in baseball integrating (and if anyone had any interesting article, books or references on the subject they could point me to).

Some background: I collect items related to baseball's integration. For me that's meant items connected to player's like Jackie, Campanella, Doby etc from the beginning of their career through their rookie season, along with items connected to the 40's barnstorming tours etc.

A couple of years back I picked up Happy Chandler's contract as commissioner of baseball. Chandler obviously was commissioner when Jackie signed and broke the color barrier, and was supportive of Robinson. Certainly, integration would have been much less likely under Landis.

Trying to decide whether to keep the contract or move it and pick up something more connected to the players. It's definitely one of the more expensive items in my collection, so the funds could go towards other items that might be "closer" to the idea of my collection.

Would love any thoughts, articles etc. Thanks!
