Otto Grashof was a German painter of the mid-nineteenth century. He is known as a draftsman, engraver, and portrait painter. He also did historical painting, battle-painting, animal studies, and landscape art. Grashof is considered one of the founders of Chilean painting.
Grashof went to St. Petersburg in 1838, where he carried out portrait commissions for the aristocracy, and some of his works ended up in the collection of Emperor Nicholas I. Later he visited Chile as well as Brazil. He held the titles of "painter to the Russian emperor and Brazilian court painter."
Albert Einstein was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics. His mass–energy equivalence formula E = mc2, which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius".
Sir John Frederick William Herschel, 1st Baronet was a British astronomer and son of the Uranus discoverer Wilhelm Herschel. He is credited with the first double star and nebula catalogues of the southern starry sky, which he observed during a five-year stay near Cape Town.
