John Cremona's Tables

1992, 97: Published extensive data about every single elliptic curves of conductor up to 1000 in a hefty book.
Used Algol68 and the ICL3980 computer (batch jobs), which limited portability; later used C++.
Subsequently extended table to conductor up to 12000 (data available on the web).
Inspiring story of me photocopying the whole book at Arizona Winter School...
