GIS history

I found on the web some interesting contributions on GIS history.

• A history by Maria Brovelli,  here.
• A paper by A.K. Deakin, here. 
• A personal view (in GIS history and future) by Joseph K. Berry,  here.

The various source origin of these contributions reflects the particular nature of this science and its community made of academics, practitioners, computer scientists, and others ...

If you want to know about the American GIS research communities, a good starting point can be the paper by Liang Mao: here.
