Dr. Thaddeus Egghead Brain is the owner of the Castle of Dr. Brain and the designer of the Island of Dr. Brain. Thaddeus E. Brain is the great-great grandson of Dr. Cranium. He is believed by many to be the greatest living eccentric mathematical genius to date. He is a world famous mad scientist (he's not really mad, just a little bothered about the world situation). His name remained relatively unknown in the game community until the release of his first game.
He is considered the greatest, wackiest inventor and scientist there has ever been (except for maybe the rest of those in his family). He is an extraordinary little man with white hair, beard, and a mustache. Rarely do people see him without his lab coat. He has devoted his life to creating wacky inventions. In fact, at a very young age he realized that he was not like most kids. While other children were learning their addition and subtraction, he was tackling algebra, trigonometry, calculus, and studying the laws of physics. He also had a strong interest in astronomy and chemistry. While other children played outdoors, he stayed in exploring mechanical devices--gears, pulley's levers and cogs. Then there were numerous electronics experiments! So very early on, he began designing the most astonishing and clever inventions you'll ever lay your eyes on!
Dr. Brain lives in an enormous castle, hidden in the mountains, not too far from former headquarters of Sierra On-line, hidden in the mountains. It is no ordinary castle either, such as a king or queen might live in. No! The castle was owned and designed by good doctor. Just imagine it! And such a tremendous, wonderful place it is too! Those who sneak up up its secluded road, can hear strange whirring sounds coming deep from within the castle and see strange glowing lights through the windows. Dr. Brain had lived there for many years and no one had been allowed inside. Most of the world never got to see inside his castle.
Needing help, he published help wanted ad in the world's newspapers, and began interviewing candidates for the position of Laboratory Assistant. His chosen applicant would help him save the world, create new amazing inventions, and clean up his secret basement lab. He asked all apply in person at The Castle of Dr. Brain. For those who couldn't make it in person he designed a virtual way to meet him, through a game, The Castle of Dr. Brain, and allow them to see his castle from the inside with their very own eyes.
