'''Glen David Brin''' (born October 6, 1950) is an American ScienceFiction writer, creator of the Literature/{{Uplift}} universe. He is also the author of a highly amusing (and packed end to end with puns and references) novel called ''Literature/ThePracticeEffect'', and wrote the story for ''VideoGame/EccoTheDolphin: Defender of the Future''.

Around the TurnOfTheMillennium, Brin gained a measure of notoriety among ''Franchise/StarWars'' fans for printing a blisteringly critical series of essays regarding that universe's philosophies and messages. He and Creator/MattStover later compiled them into a book called ''[[http://www.davidbrin.com/starwarsontrial.html Star Wars on Trial]]''.

Brin is probably the best known of the authors sometimes referred to as "the Killer B's", which also includes Creator/GregBear and Creator/GregoryBenford. The three are often credited with helping to revitalize [[MohsScaleOfScienceFictionHardness hard SF]] after the rise of {{Cyberpunk}}. They became associated when each wrote one volume of a prequel trilogy to Creator/IsaacAsimov's ''Literature/{{Foundation}}'' series.

!!Tropes found in his other works include
* AbsentAliens: A recurring theme; two instances are the short stories "The Crystal Spheres" and "Lungfish".
* {{Aesoptinum}}: "The Giving Plague".
* CyberPunk and PostCyberpunk: A recurring theme (expressly stated in his nonfiction) is that the choice between CyberPunk and PostCyberpunk depends on whether we try to restrict the benefits of technology to the "proper authorities" or make them available to everyone.
* {{Gendercide}}: In ''Glory Season'', a spaceship carrying feminist colonists goes to a far, far away planet in order to create a perfect society. The women are in charge, and whenever one of them finds their 'niche' in society, they clone themselves over and over. There are men left alive, because the scientists knew that if their society was completely stagnant, eventually something would kill them. So, there are the clone children, or "winter children" who are the majority of the population, and then "summer children" who are born when men who have proven themselves useful get to vent their genetically suppressed lusts during the summer. The summer children are also called "variants", and the protagonist's goal through the book is to find her 'niche' and be allowed to have a clone child.
* ImmortalLifeIsCheap: Explored in ''Kiln People'', in which people download their personalities into short-lived clay golems which they use for work and pleasure. While these golems are regarded as totally expendable, nobody risks his or her real self any more, and for someone to suffer even minor injury is quite a scandal.
* LivingGasbag: ''Glory Season'' has the zoor, flying jellyfish-like creatures which range from twenty meters up. Sailors like to tie ribbons and messages to their tentacles, and the larger ones can lift a child.
* PoweredByAForsakenChild:
** The key to the BigBad's plan in ''Kiln People''.
** In "Thor Meets Captain America", the Nazi Holocaust was an ambitious and successful attempt at industrial-scale necromancy.
* RuleOfFun: Makes it clear that his ''Star Wars on Trial'' articles are primarily for fun even if they're written as SeriousBusiness.
* RomanticismVsEnlightenment: His views fall firmly on the Enlightenment side, with many criticisms of Romanticism both in fiction and real life.
