Charles Henry Turner
Charles Henry Turner (February 3, 1867 – February 14, 1923) was an American zoologist, entomologist, educator, and comparative psychologist, known for his studies on the behavior of insects, particularly bees and ants. Born in Cincinnati, Turner was the first African American to receive a graduate degree at the University of Cincinnati and among the first African Americans to earn a PhD from the University of Chicago. He spent most of his career as a high-school teacher at Sumner High School in St. Louis. Turner was one of the first scientists to systematically examine the question of whether animals display complex cognition, studying arthropods such as spiders and bees. He also examined differences in behavior between individuals within a species, a precursor to the study of animal personality. This 1921 portrait photograph of Turner is in the collection of The Crisis, the magazine of the National Association for the Advancement of Colored People (NAACP).Photograph credit: The Crisis; restored by Adam Cuerden
Fixing bare URLs to prevent link rot

Bare URLs used as article references (citations) are subject to link rot. The usability of a bare URL depends entirely on the target WWW site retaining its chosen site structure, which it is under no obligation to do.

A full citation, in contrast, gives the author, title, publisher, publication, and date of the work. So, if the web site address changes, the additional information may assist in finding the new location. If the source is no longer available on the internet, then the additional information may assist in tracking down the source if it is in printed form, microfiche archives, article/paper collections, published as books, and the like. Fully dressed citations may be filled in manually, or there are semi-automated tools online, such as: reFILL (can be installed as a Toolbox link or as a Bookmarklet), or Yadkard. For Google Books, try the: Wikipedia Citation Tool for Google Books.

"The game of chess is not merely an idle amusement; several very valuable qualities of the mind are to be acquired and strengthened by it, so as to become habits ready on all occasions; for life is a kind of chess." — American philosopher, scientist, and author Benjamin Franklin
