(L to R) Dick Lathwell, Ken Iverson, Roger Moore, Adin Falkoff, Phil Abrams, and Larry Breed. (On the extreme left in the background: Jon McGrew.) Taken in the I.P. Sharp Associates hospitality suite during the 1978 APL Users Meeting in Toronto, Canada.
A slightly different version of this photo appeared on the front page of the I.P. Sharp Newsletter, 1978-11 to -12, volume 6, number 6. The caption on the photo ended with the following sentence: It is believed to be the first time all six “originators of APL” have been in the same place at the same time; it is probably the first time that all six have worn jackets and ties simultaneously and the first time Ken and Adin have been observed to smile simultaneously.
