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".
Arsène Lacarrière Latour, full name Géraud Calixte Jean Baptiste Arsène Lacarrière Latour, was a French-born American engineer and military officer, architect and surveyor, and writer.
He studied architecture and engineering at the Académie des Beaux-Arts in Paris and served briefly in the French Army Corps of Engineers. In 1805 Latour came to New York, where he worked first as a merchant, then as an architect and surveyor, and opened an architectural firm in New Orleans. In 1812. Latour became a U.S. citizen.
In 1814. Latour became Andrew Jackson's military engineer and made an important contribution to the American victory at the Battle of New Orleans. After the war ended, Latour published a book, Historical Memoirs of the War in West Florida and Louisiana, 1814-1815, which is still valued for its eye-witness view of the war.
In 1816. Latour traveled with Jean Lafitte on an expedition to survey and map the Southwest as an agent for Spain. From 1818 to 1834 he worked as an architect in Havana. His manuscripts include an extensive report describing Havana's thriving economy in 1815-1821, local agricultural production (sugar cane, coffee, tobacco), trade with Europe, the United States, and the colonies of South America; statistics; and a section on the city's possible future expansion and growth. Latour subsequently returned to France, where he died.
