No, that is NOT what I mean. What I mean is that he: 1. Established his own medical practice in Paterson, New Jersey. 2. Was appointed City Physician. 3. Founded the outpatient clinic at Paterson General Hospital. 4. Became Health Inspector in Paterson. 5. Became Health Officer in Paterson. 6. Left the city's service and became the sanitary adviser to the East Jersey Water Company. 7. Became President of the Board of Health for Paterson. He was also a member of "a large number of professional associations". There is more in the wikipedia page, but I'm getting bored. He sounds like an awesome guy and certainly somebody who specialized in public health, but there isn't a shred of evidence that he wasn't a shrewd business man. On the contrary, everything points to him being just that. As far as him not capitalizing on his invention ... he didn't invent it, by his own admission. Also, let's not forget that he developed the delivery device in the employ of the water company. It's theirs, even if there is something to patent. If you work at Microsoft and develop a piece of software in the process of working for them, they own the fruits of your labor. That's not a foreign concept to that era.
