First and foremost, we would like to acknowledge the phenomenal support of Microsoft Research who not only facilitated the acquisition of a number of the objects in the collection, but also provided the support that enabled us to build the online presence of the exhibit.

Second, we would like to thank ACM SIGCHI and the organizing committee for inviting us to be a part of CHI 11. Without that catalyst, encouragement and opportunity, we would be nowhere near where we are with this today.

Third, it is impossible to adequately thank the team, known informally as the �Buxton Army� from the Advanced Development Team in Microsoft Research, Redmond (an army in which I was a private and they all officers). They brought the entire ambitious online experience together by equal doses of determination, enthusiasm, talent, and good nature. Working with them was one of the most musical experiences of my life.

Carrying the flag and providing both the glue that held us together and the grease that kept us moving was the army�s leader, Ann Paradiso. In her posse were Tambie Angel, Tony Carbary, Ben Grefsrud, Gavin Jancke, Chuck Needham, Lynn Powers, Jim St. George, ThuVan Pham, and Curtis von Veh.

Finally, working in Toronto, the other foreigner in the army, was Katy Balderston, my daughter and full-time assistant throughout this project. Without her, nothing would have been found, much less catalogued or shipped. Her attention to detail is staggering. Actually, that is the case of every member of the team � just one of the things that makes them special.

Next I would also like to acknowledge the impact of the Bruce Mau Design Studio and the Institute Without Boundaries of having the insight to include part of the collection to have a place in the Massive Change exhibition. This helped me (Bill) realize that this was something more special than I had realized.

During the run up to this exhibit, and even before, a number of people have made generous donations of their time, knowledge, and devices, and in so doing have made a substantial contribution to the collection. These include, in no special order:

Sasha Navarro for exhibit design

Shumin Zhai, now of Google, and previously Ted�s colleague, for sharing his experience in the development of the Trackpoint Mice at IBM.
