Interesting (to me, at least) Kodak portrait lens realization

[Tin Can]

My industry often fired a top engineer and they moved to the completion

2 years later the spy was rehired

Really pissed me off, as I taught them

Sometimes I was sent to Detroit to tell them everything

Late in my career, I asked my boss why was I never promoted?

His answer was, "When you find a good horse, you ride it".

I was making more $$$ than my supervisor as I worked all possible overtime including illegal shifts

I suspect that while the Rochester lens makers were mostly competitors, sometimes they would collaborate on things. I recall a Kodak Optics old-timer once told me "they all knew each other", meaning that there was more collaboration than anyone realizes today. Your lens is a good example of that idea.
