Aperture Science

Aperture Science is an American research corporation whose laboratories and administration are located in Cleveland, Ohio, USA. Originally a shower curtain manufacturer, it evolved over the course of half a century into an experimental physics research institution and a bitter rival of Black Mesa. It was introduced on its real-world official website, ApertureScience.com, then featured in two games of The Orange Box: Portal, with the Aperture Laboratories as the game's main setting, and the Half-Life 2: Episode Two, where it is discussed near the end of the game. The Aperture Laboratories are also expected to be the main setting for Portal 2.

Cave Johnson era


In 1953, Aperture Science is founded by Cave Johnson, as a shower curtain manufacturer. The name "Aperture Science", seemingly random, is chosen "to make the curtains appear more hygienic". In 1956, the Eisenhower administration signs a contract with Aperture to manufacture shower curtains to all branches of the US Military, except the Navy. From 1957 to 1976, the company produces mostly shower curtains, eventually making Cave Johnson a billionaire. As far as 1973, the name "GLaDOS" is already used by Aperture.

In 1978, Cave Johnson is exposed to mercury while secretly developing a dangerous mercury-injected rubber sheeting from which he plans to manufacture seven deadly shower curtains to be given as gifts to each member of the House Naval Appropriations committee, likely because the decision of the Navy not getting its shower curtains from Aperture depended on that committee, and Johnson probably held a grudge against them for that. In 1979, both of Cave Johnson's kidneys fail. Brain damaged, dying, and incapable of realizing his time will come soon, he lays out a three tiered research and development program. The results, he says, will "guarantee the continued success of Aperture Science far into the fast-approaching distant past." What happens to Cave Johnson afterward is unknown, although it is surmised he dies.

The three tiers of this research and development program are:


 * Tier 1: The Heimlich Counter-Maneuver - "A reliable technique for interrupting the life-saving Heimlich Maneuver." In other words, insure choking.


 * Tier 2: The Take-A-Wish Foundation - "A charitable organization that will purchase wishes from the parents of terminally ill children and redistribute them to wish-deprived but otherwise healthy adults." It counters the real-life Make-A-Wish Foundation, designed to grant wishes to terminally ill children.


 * Tier 3: The 'Portal' project - As said by Johnson when it was first laid lout: "Some kind of rip in the fabric of space... That would... Well, it'd be like, I don't know, something that would help with the shower curtains I guess. I haven't worked this idea out as much as the wish-taking one." This is what will become the 'Portal' project, involving the Aperture Science Handheld Portal Device and its creation of portals.

Post-Cave Johnson era


In 1981, Aperture engineers complete the Heimlich Counter-Maneuver and Take-A-Wish Foundation initiatives. The company announces products related to the research in a televised ceremony. These products become immediately wildly unpopular. After a string of very public choking and despondent sick child disasters, senior company officials are summoned before a Senate investigative committee. During these proceedings, an engineer mentions that some progress has been made on Tier 3, the "man-sized ad hoc quantum tunnel through physical space with possible applications as a shower curtain." The committee is quickly permanently recessed, and Aperture is granted an open-ended contract to secretly continue research on the 'Portal' and Heimlich Counter-Maneuver projects. From 1981 to 1985, work progresses on the 'Portal' project. During this time, several high ranking Fatah personnel choke to death on lamb chunks despite the intervention of their bodyguards, showing that the US government has apparently put the Heimlich Counter-Maneuver to work.

As far as 1982, the Enrichment Center, where Test Subjects undergo tests, is functioning, as the Enrichment Center Test Subject Application is already applied at that time. It is unknown if the Enrichment Center is already "computer-aided" in 1982, as scientists have been known to supervise them from small offices until an undetermined date. The Enrichment Center Test Subject Application is operated by version 1.07 of GLaDOS, later "1.07a" and "1.09". In 1985, the Aperture Image Format is created.

In 1986, word reaches Aperture Science management that Black Mesa is working on a similar portal technology. In response to this news, Aperture Science begins developing GLaDOS. It is unknown why and how her name was already in use as far as in 1973. In 1985, the Aperture Image Format is maintained by Doug Rattmann. In 1996, after a decade spent bringing the Disk Operating System parts of GLaDOS to a state of more or less basic functionality, work begins on the Genetic Lifeform component. In 1997, GLaDOS' version is 3.11. Several years after 1996, the untested AI of GLaDOS is activated for the first time as one of the planned activities on Aperture's first annual bring-your-daughter-to-work day. This is a success.

Post-GLaDOS activation era


What happened from the late nineties and onwards is open to speculation. All that is known for certain is that at some point after her activation GLaDOS becomes self-aware, floods the Aperture Science Enrichment Center with a deadly neuro-toxin, and is subsequently fitted with a Morality Core. Later GLaDOS is still able to wrestle control of the facility from its human occupants, and presumably either kills or imprisons them. Also during or before this period, and at least before all Aperture employees disappear, the Aperture Science Handheld Portal Device is finally completed.

It is possible, however, that the lockdown of the Aperture Laboratories and subsequent death of employees is due to the in-progress Combine invasion of Earth. Indeed, the Black Mesa Incident occurs during the first decade of the 21st century, and the first Portal Storms, the Seven Hour War and the start of the Combine invasion of Earth succeed each other not long after, which would eventually set the Half-Life 2 and the Portal events not that far in time. The hacker message found on ApertureScience.com also mentions them being in lockdown for an unknown period of time, working on twenty year old equipment, and the construction of the Enrichment Center. When this message was written is unknown. As the existence of other employees and the construction of the Enrichment Center are mentioned, it was probably written before the Portal era, and before or during the troubles following the Black Mesa Incident.

Portal era


At the time of the events depicted in Portal, the Enrichment Center seems to be long abandoned, and GLaDOS seems to rule it alone, although other people are apparently still trapped somewhere. GLaDOS hints to Chell that things have changed since the last time she left the building, and that what is going on out there will make her wish she were back in here. Even though she may be completely lying, she may refer to the Combine presence outside. The scribblings left by Rattmann also seem rather old. A calendar named "The girls of Aperture Science", dated 1983, is also rather worn-out.

Portal 2 era
While it is unknown when Portal is set, Portal 2 is set "hundreds of years" later. During that time Aperture Science as it originally was likely does not exist anymore, as GLaDOS and the Personality Cores took over the partially destroyed facility. If there were other people still trapped in the facility during the Portal events, they are likely dead.

Other facts



 * Aperture Science owned a research ship, named Borealis, housing a yet to be revealed technology. It disappeared and took a chunk of its drydock with it and soon became a legend amongst the scientific community. Debate raged between Eli Vance and Isaac Kleiner over whether the technology within should be destroyed or used. Kleiner said he felt that the power could be used to destroy the Combine, but Eli seemed to suggest that he felt that trying to utilize the power could result in a repeat of the Black Mesa Incident.


 * Aperture Science and Black Mesa were bitter rivals. As seen in the Portal maps " " and " ", Aperture Science employees were briefed on Black Mesa through slideshow presentations, such as one titled "Dollar$ and Sense: Competing with Black Mesa for DoD and Government-wide Acquisition Contracts". This slideshow gives some statistics pertaining to Black Mesa, a graphic comparing the GSA schedules for both Black Mesa and Aperture Science, showing that Black Mesa did not ask much and received more or less the same, while Aperture asked a lot, and received much less than Black Mesa, and compares what Aperture and Black Mesa have to submit to the Defense Logistics Agency for developing a Fuel System Icing Inhibitor, and the role of their GLaDOS in that task. These slides show how much they were directly competing for government funding; Isaac Kleiner also theorized that the Borealis disaster may have been caused by Aperture Science's rush for such funding.

"Dollar$ and Sense" slides

 * During Chell's tests, GLaDOS mentions a "self esteem fund for girls", to which one can donate one or all of their vital organs. This is likely true, as it is apparently said as one of GLaDOS' few automatic message.


 * A memo found among the ASCII art images revealed during the Portal ARG states that Aperture Science is built on three pillars, apparently coined by Cave Johnson himself:


 * Another memo suggests that Cave Johnson had some issues with official accountants, likely responsible for founding from the state, as they seem to be an authority higher than him.


 * Another memo appears to be a letter from Johnson to several Test Subjects who raised their concerns about the dangers of the research conducted by Aperture Science.


 * As suggested in Portal, Aperture has not much concern about its Test Subjects. A memo revealed by the Portal ARG apparently consisting of the answer to a (confidential) letter received by Cave Johnson elaborates on this, and seems to describe the four types of Test Subjects and their behavior, in a not very human way. It goes as follows:

Artwork gallery
Portal is filled with Aperture Science and Aperture Laboratories logos, with numerous color variants.

Aperture Science logo variants
As with Black Mesa, the Aperture Science logo is directly based on the company's name, appearing as a stylized, partially closed diaphragm, with an aperture in the center. An "aperture" is an adjustable opening in an optical instrument, such as a camera or telescope, that controls the amount of light passing through a lens or onto a mirror. An "aperture" can also simply refer to any opening. However the name "Aperture Science" is likely random, as it was merely chosen for its shower curtains to appear "more hygienic". Dog's unique eye is also an aperture in a diaphragm; the Emergency Intelligence Incinerator is also topped by a diaphragm. Furthermore, real-life logos such as the Picasa or the Jyske Bank logos bear similarities with the Aperture Science logo.

Aperture Laboratories logo variants
The Aperture Laboratories logo features the Aperture Science "diaphragm", minus one of its irises, and the words "Aperture Laboratories", written in the fonts Segoe and Helvetica, respectively.
