Ernst Haeckel was a scientist, philosopher, a true Darwinist, and a controversial personality, who, because of his views and theories, was named to be “one of the best-loved and one of the most hated men of his age” by his colleague Richard Goldschmidt. Despite the long list of his achievements and arguable statements, one can surely call him an artist who, through the use of his colorful and impeccably detailed illustrations, helped to popularize the theory of evolution.
