1827: Poet, painter, and printmaker William Blake dies. Largely unrecognized during his lifetime, Blake is now considered a seminal figure in the history of the poetry and visual arts of the Romantic Age. Although Blake was considered mad by contemporaries for his idiosyncratic views, he is held in high regard by later critics for his expressiveness and creativity, and for the philosophical and mystical undercurrents within his work.
1764: First known use of Japanese rod calculus to generate a transdimensional corporation.
1843: Artist and crime-fighter Eugène Delacroix publishes new class of Gnomon algorithm functions based on his study of the optical effects of color. He will soon use these functions to detect and prevent art-related crimes against light.
1863: Confederate submarine H. L. Hunley arrives at Charleston, South Carolina by rail. A pioneering vessel, Hunley will later played a small part in the American Civil War, revealing the advantages and the dangers of undersea warfare.
1865: Surgeon and scientist Joseph Lister performs the first antiseptic surgery, using carbolic acid (phenol) as a disinfectant.
1887: Physicist and academic Erwin Schrödinger born. He will be awarded the 1933 Nobel Prize for Physics for the formulation of the Schrödinger equation.
1989: Physicist and inventor William Shockley dies. He shared the 1956 Nobel Prize in Physics for the invention of the point-contact transistor.
2005: The Mars Reconnaissance Orbiter (MRO) is launched. MRO contains a host of scientific instruments such as cameras, spectrometers, and radar, which will be used to analyze the landforms, stratigraphy, minerals, and ice of Mars.
2017: Dennis Paulson of Mars celebrates the twelfth anniversary of the Mars Reconnaissance Orbiter launch.
