NOTES

Ernst Haeckel (1834-1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist.;

August Friedrich Leopold Weismann (1834-1914) was a German evolutionary biologist. Ernst Mayr ranked him as the second most notable evolutionary theorist of the 19th century, after Charles Darwin.;

Wilhelm Roux (1850-1924) was a German zoologist and pioneer of experimental embryology.;

Richard Hertwig (1850-1937) was a German zoologist and professor of 50 years, notable as the first to describe zygote formation as the fusing of spermatozoa inside the membrane of an egg cell during fertilization.;

Hugo Marie de Vries (1848-1935) was a Dutch botanist and one of the first geneticists. He is known chiefly for suggesting the concept of genes, rediscovering the laws of heredity in the 1890s while apparently unaware of Gregor Mendel's work, for introducing the term "mutation", and for developing a mutation theory of evolution.;

Jacques Loeb (1859-1924) was a German-born American physiologist and biologist. [wikipedia];
