In 1986, word reaches Aperture Science management that Black Mesa is working on similar portal technology. In 1985, the Aperture Image Format is maintained by Doug Rattmann. In 1985, the Aperture Image Format is created. The Enrichment Center Test Subject Application is operated by version 1.07 of GLaDOS, later "1.07a" and "1.09". It is unknown if the Enrichment Center is already "computer-aided" in 1982, as scientists have been known to supervise Test Subjects from small offices until an undetermined date. He dies of moon-rock poisoning one year later.Īs far as 1982, the Enrichment Center, where Test Subjects undergo tests, is functioning, as the Enrichment Center Test Subject Application Process, a 50-question questionnaire destined for applying Test Subjects, is already used at that time. ( Propulsion Gel was released around this time too.)īy 1981, Cave Johnson was exposed to toxic Conversion Gel, made out of ground-up moon rocks. Cave suspects Black Mesa of industrial espionage on the company's products, and blames them for Aperture's bankruptcy. At first only the brightest and best of society were chosen for testing (such as Astronauts, Olympians, and War Heroes) but after being connected to a string of astronaut disappearances in 1968, Aperture Science focused on recruiting homeless people for testing, starting in 1972. Repulsion Gel was first developed around this time as well for use as a diet supplement. Įarly work on the Aperture Science Handheld Portal Device began the early version, called the Aperture Science Portable Quantum Tunneling Device, proved to be too bulky for effective use, while poor surface conductors for the portals often caused mangling or death of the test subjects when they tried to use the portals. In 1956, the Eisenhower administration signs a contract with Aperture to manufacture shower curtains to all branches of the US Military, except the Navy. In 1947, Cave Johnson purchased an abandoned salt mine that ran over 4200 meters underground in order to create the facility for Aperture Science. Johnson renamed the company "Aperture Science Innovators" in 1947, also for the same purpose of making the curtains appear more hygienic. In the late 1940's, Aperture Fixtures was founded by Cave Johnson as a shower curtain manufacturer (The name "Aperture Fixtures" was chosen "to make the curtains appear more hygienic" ). 3.2 Aperture Laboratories logo variants.
