# Credits¶

NetworkX was originally written by Aric Hagberg, Dan Schult, and Pieter Swart, and has been developed with the help of many others.

Thanks to Guido van Rossum for the idea of using Python for implementing a graph data structure http://www.python.org/doc/essays/graphs.html

Thanks to David Eppstein for the idea of representing a graph G so that “for n in G” loops over the nodes in G and G[n] are node n’s neighbors.

Thanks to everyone who has improved NetworkX by contributing code, bug reports (and fixes), documentation, and input on design, featues, and the future of NetworkX.

Thanks especially to the following contributors:

- Katy Bold contributed the Karate Club graph.
- Hernan Rozenfeld added dorogovtsev_goltsev_mendes_graph and did stress testing.

- Jim Bagrow reported bugs in the search methods.
- Holly Johnsen helped fix the path based centrality measures.
- Arnar Flatberg fixed the graph laplacian routines.
