Welcome

IM2019 Want to know more about the history of calculating instruments? Come to the International Meeting of Collectors of Calculating Instruments, September 20 to 22, 2019, in The Hague/Scheveningen
Welcome to this collection of papers I wrote on historical calculating machines and mathematical instruments.
Most of them have appeared in Dutch in the "Mededelingen en Informatie voor Rekenlinialenverzamelaars" (MIR)

You might also be interested in original documents on calculating history or the Rechnerlexikon, a wikipedia for calculating devices, or the Oughtred Society.

If you have any comments, please leave them in the form at the right.
