File:William Blake by John Flaxman c1804.jpg|link=William Blake (nonfiction)|1827: Poet, painter, and printmaker [[William Blake (nonfiction)|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.

||1960: The U.S. launched the first telecommunications satellite, Echo 1, from Cape Canaveral, packed in a Thor-Delta rocket. At the altitude for low Earth orbit, above almost all of the Earth's atmosphere, the satellite was deployed and inflated with gas at low pressure to form a 100-ft (30.5-m) diameter spherical balloon made of metallized Mylar, 0.5 mils (12.7-μm) thick. Thus it is known as a balloon satellite, as originally conceived by William J. O'Sullivan (26 Jan 1956). Its orbit was at about 1,000 miles (1600-km). It was merely passive, to reflect microwave signals between points on Earth, similar to the way the Moon reflects light while the Sun is below the horizon. A commemorative stamp was issued 15 Dec 1960. Echo 1 remained in orbit until 24 May 1968. Telstar 1 followed 10 Jul 1962.
