Benjamin Gompertz (March_5. 1779 - July_14, 1865, London, England), self educated mathematician denied admission to universities since he was Jewish. Fellow of the Royal Society from 1819. Gompertz is today mostly known for his Gompertz' law of mortality, a demograhic model published in 1825. The model can be written in this way:
<math>N'(t) = -r N(t) \log \left( \frac {N(t)}{K} \right)\, <math>
where <math>N(t)<math> represents number of individuals at time t, r the intrinsic growth rate and K number of individuals in equilibrium.
