Two lives remembered - in Science:
One real - one fiction - both consequential:

Dmitri Ivanovich Mendeleev (Russian: Дми́трий Ива́нович Менделе́ев, 8 February 1834 – 2 February 1907 O.S. 27 January 1834 – 20 January 1907) was a Russian chemist and inventor. He formulated the Periodic Law, created his own version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of elements yet to be discovered.

Jules Gabriel Verne (8 February 1828 – 24 March 1905)was a French novelist, poet, and playwright best known for his adventure novels and his profound influence on the literary genre of science fiction.

Verne was trained to follow in his father's footsteps as a lawyer, but quit the profession early in life to write for magazines and the stage. His collaboration with the publisher Pierre-Jules Hetzel led to the creation of the Voyages Extraordinaires, a widely popular series of scrupulously researched adventure novels including Journey to the Center of the Earth, Twenty Thousand Leagues Under the Sea, and Around the World in Eighty Days.

Verne is generally considered a major literary author in France and most of Europe, where he has had a wide influence on the literary avant-garde and on surrealism. His reputation is markedly different in Anglophone regions, where he has often been labeled a writer of genre fiction or children's books, not least because of the highly abridged and altered translations in which his novels are often reprinted.

Verne is the second most-translated author in the world since 1979, between the English-language writers Agatha Christie and William Shakespeare, and probably was the most-translated during the 1960s and 1970s. He is one of the authors sometimes called "The Father of Science Fiction", as are H. G. Wells and Hugo Gernsback.
