Congratulations to Dan Smith who was the first to correctly identify the
mystery photograph as Paul Eisler, father of the PCB.
No invention occurs on a single date, but this month does see the 60 th
anniversary of a major milestone, namely the publication on June 21, 1950 of
Eisler's first PCB patents.
