I don't know very many scientists to start off with, so the only person I could really think of would be, Dmitri Mendeleev. He has made a large impact on what science is today, he practically made chemistry and taught the world what he learned. The things we eat, things we see daily and the objects we use on a daily basis are explained to the public because of him. Regular house hold items don't have to just be looked at as just an item, he created a deeper meaning and allowed others to discover and learn as well. His knowledge is greater than we can imagine, With the information he gathered about the elements, he was able to see that there were missing elements that hadn't been discovered. He could figure out the atomic masses of the missing elements by averaging the atomic masses of the elements above and below the missing one. Throughout the years, other scientists were able to find or create these missing elements to form the table we know today. Today's periodic table is ordered by atomic number instead of atomic mass as Mendeleev had started and others have continued on. He made one of the greatest discoveries of all time and taught all that he knew to the public and made a direct impact on the science community and every day life today.
