#18. Ernest Haeckel (1834-1919): One of The Fathers of Zoology
What makes Ernest Haeckel famous?
In the late 1800s, German zoologist and physician Ernest Haeckel wasn’t just a man of science but had truly mastered it.
Haeckel was the first to coin the term “ecology.” But he is best known for creating one of the foremost genealogical trees for humans.
As a proponent of Charles Darwin’s theories, Haeckel popularized Darwinism in his country. His least popular work involved recapitulation theory. This is the idea that an organism’s embryological development parallels its evolutionary history.
He was also known as one of the fathers of eugenics. This movement sought to improve human genetics by promoting reproduction between individuals with desirable traits. But despite this legacy, many consider Haeckel one of the most influential biologists of all time.

#5. Charles Darwin (1809-1882): The Father of Evolution
What makes Charles Darwin famous?
Charles Darwin was an English biologist, naturalist, and geologist who contributed significantly to evolutionary biology through his theory of natural selection.
This theory states that individuals best suited to survive and reproduce will pass on their genes to future generations, while those less fit will not succeed as well as others. The result is that certain traits become more common over time because of this process of natural selection.
Darwin believed that all living things originated from one ancestor. He also wrote On the Origin of Species, which became one of the most influential books ever written on evolution—and it still is today.
What’s the best Charles Darwin quote?
“It’s not the strongest of species that survive, nor the most intelligent, but the one most responsive to change.”

#4. Paul Ehrlich (1854-1915): The Discoverer of Syphilis Treatment
What makes Paul Ehrlich famous?
Paul Ehrlich was a German physician. He is notable for his research on antimicrobial chemotherapy, immunology, and hematology.
In 1909, Ehrlich discovered that treating syphilis with arsphenamine could cure it. This treatment was so effective that even when patients went untreated for years, they would still be cured if they received treatment after being treated for syphilis.
He also made significant contributions to staining techniques, making it possible for medical scientists to diagnose diseases like cancer and leukemia more accurately than ever before.
As part of his work, Ehrlich formed and popularized his concept of a magic bullet. He believed medical doctors could kill the disease-causing microbes without harming the patient’s body.
Paul Ehrlich received the Nobel Prize in Physiology or Medicine in 1908 for his research, which has taken medicine to the next level in treating and diagnosing diseases.

#3. Thomas Hunt Morgan (1866-1945): The Nobel Laureate & An Expert in Heredity
What makes Thomas Hunt Morgan famous?
Thomas Hunt Morgan was an American geneticist and evolutionary biologist best known for his work on the fruit fly. He laid the foundation of modern genetics.
Morgan was born in Kentucky, USA, on September 25, 1866, and studied at Johns Hopkins University, earning his P.h.D. His research focused on understanding the mechanisms of heredity as well as how genes are passed from one generation to another.
This finding led him to discover that chromosomes contain genes and that each chromosome carries only one kind of gene pair (a dominant and recessive gene).
Morgan also found that genes are arranged linearly along chromosomes and can be inherited together or independently. In 1933, Morgan received the Nobel Prize in Physiology or Medicine for his work on chromosomes and their function in heredity.
