Eric Bernard Iverson is a co-owner of Jsoftware, primary implementer of J's session environment, and son of Ken Iverson. Before starting Jsoftware he contributed to SHARP APL as an implementor and development manager at IPSA.
Iverson left his studies at Yale University in 1968 to join I.P. Sharp Associates, where he did implementation work on APL\1130 and a rewrite of APL\360 for small machines. His work with Larry Breed on a shared file system for APL was demonstrated by Al Rose and Breed at APL70, the second APL conference. Among other management positions, Iverson managed SHARP APL development from 1974 to 1984.
Iverson left I.P. Sharp in 1990 to found Iverson Software, Inc. to provide an improved Sharp APL/PC product (APLIWIN) for Microsoft Windows. The company would later be named Jsoftware to focus on J. Iverson has worked on various IDEs for J including the original Windows-based environment, GTK- and Qt-based IDEs, and the HTML-based JHS, and is a co-developer of the Jd database management system. In 1999 he was appointed CTO of Adaytum Software, a company which relied heavily on J.
