This is JaydenCreepypasta2009's Timeline of the Half-Life & Portal universes.

1953

 * Cave Johnson receives the Shower Curtain Salesman award within Aperture Fixtures.

January

 * Cave Johnson appears in the UP Pioneer Press headlines for buying a salt mine in Upper Michigan, which is later reconstructed as the Aperture Science Innovators facility.

Between 1954 and 1957

 * Richard Keller is born.

Between 1957 and 1960

 * Wallace Breen is born

1957

 * Aperture Science receives the award for Best New Science Company from the Science and Business Institute of America.

1959

 * Aperture Science is rated #2 among the Top 100 Applied Science Companies by the Mechanical Engineering World Journal.

1960s
It is during this decade that the Black Mesa facilities are probably built, before being purchased and refurbished later by Black Mesa (several Half-Life texture files names contain the word "sixties", suggesting the facility is as old as from the 1960s).

1962

 * Aperture Science is the Runner Up for the US Department of Defense's Contractor of the Year award. By now, Aperture Science has begun testing Repulsion Gel.

1963

 * Aperture Science constructs Pump Station Alpha and at least Test Shaft 09 Chambers 01 and 02.

1964

 * Aperture Science is the Runner Up for the US Department of Defense's Contractor of the Year award again.

1965

 * Aperture Science receives the Spirit of Idaho National Potato Board award for the promotion of Potato Science.

1966

 * The Eisenhower administration signs a contract with Aperture Science to manufacture shower curtains to all branches of the US Military, except the Navy.
 * Pump Station Alpha (which pumps Repulsion Gel) is in active use by now.

1967

 * Aperture Science constructs at least Test Shaft 09 Chamber 26.

1968

 * Aperture Science constructs Test Shaft 09 Chambers 27 and 28.

Between 1969 and 1978

 * Ms. Johnson is born

Between 1970 and 1979

 * Joel Gasley is born

March 15

 * Aperture Science's Test Shaft 09 "Zulu Bunsen" is condemned and sealed off.

Between 1976 and 1984

 * Isaac Kleiner is born

1978

 * Aperture Science is involved in US Senate hearings regarding "missing astronauts". By now, Aperture Science has gone black bankrupt. Cave Johnson says that Black Mesa has stolen and remade many of Aperture's products.

Between 1978 and 1988

 * Colette Green is born.

1979

 * Apollo 11 lands on the Moon.

1981

 * Aperture Science re-opens Test Shaft 09 for testing. The lower sections appear to remain unused.
 * Aperture constructs Pump Station Beta and begins Propulsion Gel testing.

1982

 * Aperture Science constructs at least Chambers 01 and 02 of the Propulsion Gel Testing Facility.
 * Colette Green is born.

1983

 * This date is the earliest known use of a bulletin board system by Aperture Science.

Between 1984 and 1994

 * Gina Cross is born.

Between 1982 and 1992

 * Gordon Freeman is born.

1986

 * Aperture Science constructs Chamber 05 of the Propulsion Gel Testing Facility.

October 17

 * Cave Johnson receives the answer to a confidential letter titled "Human Enrichment & Testing Initiative, Resource Acquisitions", describing the four types of Test Subjects and their behavior.

1988

 * Aperture Science constructs the elevator out of the Propulsion Gel Testing Facility.

Between 1987 and 1990

 * Adrian Shephard is born.

1991

 * Aperture Science constructs the Conversion Gel Testing Facility's enrichment center, and now performs tests on its own employees. By now, Cave Johnson has spent $70 million on moon rocks to grind up and turn into Conversion Gel, and as a result of exposure has himself become gravely ill and addicted to pain medication.

1992

 * Aperture Science constructs Pump Station Gamma and the Conversion Gel Testing Facility.
 * Cave Johnson names Caroline as his successor. When testing is complete, her intelligence is to be stored in his computer. Shortly after this announcement, he succumbs to moon rock poisoning and dies.

1993

 * For this year, a calendar named "The girls of Aperture Science" is issued by Aperture Science. It is unknown if it was issued each year.

Between 1995 and 2004

 * Kayden Anderson is born

1995

 * The Aperture Image Format is created.

1996

 * The Conversion Gel Testing Facility is updated with an additional wall.
 * 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, although the name was already in use in 1982. GLaDOS V.1 is activated, and (for the first time) attempts to kill all the staff of Aperture Science.

1997

 * This is the most recent date for the Aperture Image Format. At that time, it is maintained by Doug Rattmann.


 * Sometime in this time period, Cave Johnson dies of moon-rock poisoning. It is unspecified when exactly it happened.
 * The Borealis is claimed lost at sea. It is also unspecified when exactly this occurred.

Between 1998 and 2007

 * Chell is born

2000s

 * Judging from Chell's handwriting and spelling skills, she is under the age of ten, meaning that the Aperture Science Bring Your Daughter to Work Day event occurs sometime early in this decade, and ends in an unspecified disaster.

Between 2005 and 2015

 * Alyx Vance is born.

2006

 * The Aperture Science Red Phone plan is implemented in case GLaDOS appears to become sentient and godlike, requiring an employee to sit by a red phone on a desk in GLaDOS chamber's entrance hall.

2007

 * At this time, GLaDOS's version is 3.11. This is also the latest known date of Aperture Science using a bulletin board system.

2008

 * Aperture Science releases several testing elements, such as the Excursion Funnel, a tractor beam-like funnel made of liquid asbestos, the Thermal Discouragement Beam, a laser to be used with a Weighted Pivot Cube to destroy Sentry Guns and activate some buttons, the Aerial Faith Plate, a catapult plate flinging into the air Test Subjects or any other object upon contact, and the Pneumatic Diversity Vent, a variant of the Vital Apparatus Vent used for distributing objects to Test Chambers.

Between 2008 and 2017

 * Ellis Parker is born
