An oral history of Bank Python
I was the person who first deployed Python at Goldman Sachs. At the time it was an "unapproved technology" but the partner in charge of my division called me and said (This is literally word for word because partners didn't call me every day so I remember)    Err....hi Sean, It's Armen.  Uhh.... So I heard you like python.... well if someone was to uhh.... install python on the train... they probably wouldn't be fired.  Ok bye.

"Installing python on the train" meant pushing it out to all the computers globally in the securities division that did risk and pricing.  Within 30mins every computer in goldman sachs's securities division had python and I was the guy responsible for keeping the canonical python distribution up to date with the right set of modules etc on Linux, Solaris and Windows.Because it was unapproved technology I had a stream of people from technology coming to my desk to say I shouldn't have done it.  I redirected them to Armen (who was a very important dude that everyone was frightened of).The core engineers from GS went on to build the Athena system at JP and the Quartz platform at BAML.//Edit for grammar
