Nathaniel Essex was a biologist in Victorian England who developed advanced theories on human evolution and was obsessed with Darwin’s theory of evolution, though he felt Darwin and his contemporaries were shackled by too many moral constraints. While pursuing his own research in 1859, he discovered that humanity was undergoing increasing mutation, due to what he called “Essex Factors” in the human genome. His theories were mocked, making him bitter. His son’s death (at the age of four from numerous birth defects, including crooked bones & hemophilia) drove him deeper into his work. He approached many groups in search of funding, including the Hellfire Club, though all turned him down. He hired a group of thugs, whom he named Marauders, to kidnap people off the streets of London so he could perform experiments on them; he even went so far as to dig up his dead son and experiment on him. A geneticist of unparalleled genius, he foresaw the coming mutations that would transform mankind. However, his unorthodox experiments resulted in his ouster from the Royal Society and caused his wife to shun him. These rejections led him to ally himself with Apocalypse, an immortal mutant who has witnessed virtually the whole of human history. Apocalypse transformed Essex into an ageless being of extraordinary pallor at the cost of what remained of his humanity. With his new abilities and dispassionate outlook, Essex took a new name—Sinister, the last word his wife spoke to him as she died, after discovering the horrors he’d been engaged in (the stress also caused her to miscarry their unnamed child).
