Antoine-Henri Becquerel

Antoine-Henri Becquerel discovered natural radioactivity from uranium in1896. A uranium compound exposed a photographic plate through a lightproofwrapper.Becquerel was having a go,At what made substances glow,With uranium he played,And discoveries he made,But that was the end of his show.Cyrus Hall McCormick invented his harvesting machine, the reaper, in 1831.The reaper revolutionized farming, by allowing fewer workers to operatelarger farms.McCormick invented the reaper,And the wheat fields grew wider and deeper,The farmers got lazy,And drank themselves hazy,But his gadget was still a keeper.
