Why is Harish-Chandra's last name never used? This is only barely a math question but I don't know where else to ask. I've always wondered about Harish-Chandra's name. The Wikipedia article seems to mention "Mehrotra" as a last name but only in passing, and it's not even used in the page's title. Did he simply not use a last name? 

During the independence movement, Harish-Chandra's father under the influence of Mahatma Gandhi decided to do away with using the caste name 'Mehrotra' as also started using Khadi attire. As for the hyphen it was a mistake by a sub-editor publishing his first paper but Harishchandra decided to retain it.
