1.. _about: 2 3About us 4======== 5 6History 7------- 8 9This project was started in 2007 as a Google Summer of Code project by 10David Cournapeau. Later that year, Matthieu Brucher started work on 11this project as part of his thesis. 12 13In 2010 Fabian Pedregosa, Gael Varoquaux, Alexandre Gramfort and Vincent 14Michel of INRIA took leadership of the project and made the first public 15release, February the 1st 2010. Since then, several releases have appeared 16following a ~ 3-month cycle, and a thriving international community has 17been leading the development. 18 19Governance 20---------- 21 22The decision
