The Tartan magazine at SFU published a great article on the history of the various busts at SFU, written by Brad Mcleod. A PDF of this article is also available. The article offers a great history on how the Gandhi Bust was commissioned and how it came to be placed at SFU.
Below is a picture of the bust with Deviben Thakore placing a garland on the bust.
