Sagot :
If you say Founding Father of Biology, it's Aristotle because he contributed to differentiating different plants and animals at around 300+ BC. But if it's under the branches of Biology, one example is Gregor Mendel who is the father of Genetics and Charles Darwin who is said to be the Father of Evolution (wrong post XD i meant this for another post hountoni gomenasaia)
Herodotus is said to be the father of modern history (he recorded the greeks battling the persians)
