If memory serves, Frank had an old friend who left IBM and returned to the PNW. Frank told him about the difficulties WDF was having when trying to mark large groups of smolts for fishery studies. Together, they came up with coded wire tags. The friend started Northwest Marine Technology and invented ways to manufacture the coded tags from small gage stainless steel wire and the machine to insert the tags into the snouts of juvenile salmon. I once visited his home and small factory on Shaw Island in the San Juans. NMT produced tags and machines used for tagging juvenile fish world wide. It's cool that Frank had a hand in developing that.
