While scientists are known to be super-intelligent individuals with an understanding of such things that many other people are unable to comprehend, they have also come up with ideas that people have found to be quite crazy. Many of their beliefs, theories, or ideas have faced controversies. Let us look at a few such scientists that are termed to be most controversial in history.

Demikhov was a Soviet surgeon that went into controversies by creating a dog with two heads. He had actually grafted a puppy’s head onto a dog’s neck. However, the second head could only have milk to dribble down its neck and received no nourishment from it. While tissue rejection led to the early death of both the animals, Demikhov kept on creating many such breeds over a period of 15 years.

While he is known as the father of evolution because of his theory of evolution on the origin of species, he probably remained the most in controversies. The theory was so intensely debated that Darwin was even doubtful of publishing it. Though it was later accepted by the scientific community, it is still a topic of debates.
Many scientists have seen the challenges of controversies made against their inventions and discoveries. Still, many of them were able to prove their work right and made their names in history.
