Lead: In the 19th and 20th centuries, theories about the way to improve the human condition spawned the pseudo-science of eugenics. Unfortunately, optimism about making mankind better degenerated into the darkness of racism.

Intro.: A Moment in Time with Dan Roberts.

Content: Sir Francis Galton confessed to having had a happy childhood. His upper-class parents gave him a Cambridge education though he never took his degree, and left him sufficient inherited funds so that he could avoid work and indulge his great love of travel. From 1845 to 1853 Galton explored parts of the Middle East and Africa, including a very careful but ultimately fruitless expedition from West Africa in search of Lake Ngami, which is in Botswana, north of the Kalahari Desert. After his marriage he turned to more scholarly pursuits producing books on a wide variety of subjects including fingerprinting, calculus, genetics and weather prediction. Galton is best known, however, for his advocacy of improving the human species through selective parenting, a process he called eugenics.
