The series started after Joel Wittenberg contacted [[Dyalog Ltd.]], wanting to reconnect with the APL community. He started the [[APL Dinosaurs]] Facebook group, and suggested a live meeting. Via Zoom, he met with his friend Harry Saal and Dyalog employee Adám Brudzewsky for an hour on May 9, 2021. The meeting was deemed so enjoyable, that the group decided to make it a scheduled recurring event.
