Question: Who founded the developer of Space Spartans?

full_context: Document 1: Toys "R" Us: Founded by Charles Lazarus in its modern incarnation in 1957, Toys ``R ''Us traced its origins to Lazarus's children's furniture store, which he started in 1948. He added toys to his offering, and eventually shifted his focus. The company had been in the toy business for more than 65 years and operated around 800 stores in the United States and around 800 outside the US, although these numbers have steadily decreased with time.
Document 2: Intellivision: The Intellivision is a home video game console released by Mattel Electronics in 1979. The name "Intellivision" is a portmanteau of "intelligent television". Development of the console began in 1977, the same year as the introduction of its main competitor, the Atari 2600. In 1984 Mattel sold their video game assets to a former Mattel Electronics executive and investors that would become INTV Corporation. Games development started in 1978 and continued until 1990 when the Intellivision was discontinued. From 1980 to 1983 over 3 million Intellivision units were sold.
Document 3: Beanie Babies: Nine original Beanie Babies were launched in 1993: Legs the Frog, Squealer the Pig, Spot the Dog, Flash the Orca, Splash the Whale, Chocolate the Moose, Patti the Platypus, Brownie the Bear (later renamed ``Cubbie ''), and Pinchers the Lobster (with some tag errors with`` Punchers''). They were not in factory production until 1994. Sales were slow at first to the point that by 1995 many retailers refused to buy the products in the bundles Ty offered them while others outright refused to buy them in any form. The popularity soon grew however, first starting locally in Chicago before growing into a national craze in the USA.
Document 4: Elliot Handler: Elliot Handler (April 9, 1916 – July 21, 2011) was an American inventor, businessman, and co-founder of Mattel. With his wife, he developed some of the biggest-selling toys in American history, including Barbie, Chatty Cathy, Creepy Crawlers, and Hot Wheels.
Document 5: Sea Battle: Sea Battle is a multiplayer strategy game released by Mattel for its Intellivision video game system in 1980. In the game, players command fleets of naval vessels attempting to invade the harbor of their opponent.
Document 6: First-person shooter: The earliest two documented first - person shooter video games are Maze War and Spasim. Maze War features on - foot gameplay that evokes modern first - person shooter games. Development of the game began in 1973 and its exact date of completion is unknown. Spasim had a documented debut at the University of Illinois in 1974. The game was a rudimentary space flight simulator, which featured a first - person perspective. They were distinct from modern first - person shooters, involving simple tile - based movement where the player could only move from square to square and turn in 90 - degree increments. Spasim led to more detailed combat flight simulators and eventually to a tank simulator, developed for the U.S. Army, in the later 1970s. These games were not available to consumers, however, and it was not until 1980 that a tank video game, Battlezone, was released in arcades. A version of the game was released in 1983 for home computers and became the first successful mass - market game featuring a first - person viewpoint and wireframe 3D graphics, presented using a vector graphics display.
Document 7: Master of Orion: "Master of Orion" is a significantly expanded and refined version of the prototype/predecessor game "Star Lords" (not to be confused with "Starlord", also released by MicroProse in 1993).

Emrich and Hughes later wrote the strategy guide for the finished product. MicroProse published the final version of the game in 1994.

Presently Teddy Ruxpin is available from Wicked Cool Toys.
Document 10: History of video games: The first games known to incorporate a monitor were two research projects completed in 1952, a checkers program by Christopher Strachey on the Ferranti Mark 1 and a tic - tac - toe program called OXO by Alexander Douglas on the EDSAC. Both of these programs used a relatively static display to track the current state of the game board. The first known game incorporating graphics that updated in real time was a pool game programmed by William Brown and Ted Lewis specifically for a demonstration of the MIDSAC computer at the University of Michigan in 1954.

Document 14: Starflight: "Starflight" was developed by Binary Systems, a five-man team consisting of Rod McConnell, Greg Johnson (lead designer), Alec Kercso (programming), Tim C. Lee (graphics and programming), and Bob Gonsalves (sound). Then-vice president of Electronic Arts Joe Ybarra was also closely involved, and produced the work. The original idea for making a video game was conceived by McConnell and Ybarra in 1983. McConnell hired colleague Dave Boulton, who had an idea for using fractals to generate an endless virtual universe, along with Kercso, Gonsalves, Lee, and Johnson, all of whom were first time game designers. Boulton quit the project early on in development, saying it was too ambitious, with Lee replacing him.
