Historical Note
With an undergraduate degree from Dartmouth College and graduate degrees from the University of Rochester, followed by several years of college teaching, Dr. Andrew Longacre finally settled into his ultimate career in 1980 as a technical contributor at Welch Allyn (exactly at the juncture when they acquired the Codabar product line from Monarch Marking). As a charter member of AIM’s Technical Symbology Committee in 1982, Dr. Longacre helped to grow and standardize the many barcode symbologies now common in the industry, contributing to the early standards for 1D symbol verification, creating the first self-contained PDF-417 reader, and helping to design Channel Code (which begat RSS), Aztec Code, and most recently DotCode. He retired from Honeywell in 2008 and is now happily settled with his wife Ginny in southwestern Vermont.
