About us#

History#

This project was started in 2007 as a Google Summer of Code project by David Cournapeau. Later that year, Matthieu Brucher started working on this project as part of his thesis.

In 2010 Fabian Pedregosa, Gael Varoquaux, Alexandre Gramfort and Vincent Michel of INRIA took leadership of the project and made the first public release, February the 1st 2010. Since then, several releases have appeared following an approximately 3-month cycle, and a thriving international community has been leading the development. As a result, INRIA holds the copyright over the work done by people who were employed by INRIA at the time of the contribution.
