Weirich was the Chief Scientist at Neo Innovation, working at Neo's Cincinnati office. He also built and maintained many open source tools, the most popular being Rake and Builder with 74 and 54 million downloads, respectively.[9]


Rake is a build tool for automating tasks in Ruby.[10][11] It is the most widely downloaded Ruby Gem, downloaded more than 74 million times[12] and has been included with Apple OS X since at least version 10.7.[13]


Builder is a tool for creating structured XML data through Ruby.[14]


RubyGems is package management tool for Ruby programs and libraries. Ryan Leavengood is credited with creating the very first RubyGems project in 2001, but it did not gain enough momentum to take off. In November 2003 with the need for a proper package manager growing, Richard Kilmer, Chad Fowler, David Black, Paul Brannan, and Jim Weirich got together at RubyConf 2003 in Austin and built today's RubyGems, which shares a name, but not the original codebase.[15]

Personal life

Weirich grew up in Shipshewana, Indiana, graduating from Westview Junior - Senior High School in 1975. He went on to graduate from Indiana University in 1979 with a degree in physics. He lived in Cincinnati, Ohio.[17]

Weirich was active in the Ruby community worldwide, and especially in Cincinnati, participating in the local agile development, Ruby, and functional programming user groups. At meetings, he often gave talks and was widely acclaimed for the clarity and quality of his presentations.

News of Weirich's death was met with hundreds of tributes and thanks via comments on his final GitHub commit, which includes a special banner added by GitHub. The 1.9.3-p545 release of the Ruby programming language was dedicated to his memory.[18]
