POLYCHROME People 3

POLYCHROME People 3     As recalled by Bob Gumbinner

Ed Fritz: He had been a Vice-President of Enco, a subsidiary of Kalle Germany who had invented the negative and positive diazos used as the sensitizers for the plates. Mr. Halpern let him make changes in our production processes. These changes resulted in a loss of three-quarters of a million dollars in defective plates. When I was allowed to check up on Ed Fritz, I found that he had been the sales manager and had never been involved with the manufacturing. He was let go by Enco because of excessive drinking.

Leon Katz: He was appointed a Vice President and research director. He had been a Vice President of GAF. He did not set up or direct our research. When I checked with some of the GAF personnel, they were unable to tell me of any contributions for which he was responsible.

(One of his contribution was the suggestion to use amphoteric surfactant in our developer, till then we had not investigated the use of this fourth kind of surfactant after anionic, cationic and nonionic.     The amphoteric surfactant have both anionic and cationic properties and we have since then used this extensively in our developer system......sorry too much technical stuff!        Ken)
