What is a Gompertz model? Or what Journal was it published in?

Thank you Dr. Nelson.
You are welcome, below is a paper (not the greatest copy of it). I believe Berger might have been one of the first phytopathologists to use the Gompertz model in the early 1980s:

I think a Brit developed the model for actuarial tables. Plant pathologists often borrow useful population growth models from other disciplines. Usually these nonlinear models are linearized before using them in regression analysis, as Berger did.
