Alfred J. Lotka was an American mathematician and statistician, born on March 2, 1880, in New York City. He is best known for his contributions to the fields of population dynamics and ecology, particularly through the development of the Lotka-Volterra equations, which describe the interactions between predator and prey species. His work laid the foundation for understanding biological systems and their growth patterns. In addition to his ecological research, Lotka made significant contributions to demography and biostatistics. He introduced the concept of the Lotka's law, which describes the distribution of scientific productivity among researchers. His interdisciplinary approach has influenced various fields, including economics and sociology, making his work relevant beyond mathematics.
