Other inventions began to make way, but not always as expected. Around that time, work began on the Aperture Science Portable Quantum Tunneling Device, which was intended to serve as an interdimensional portal-creating device (that would eventually become the Aperture Science Handheld Portal Device).
In 1947, Cave Johnson purchased an abandoned salt mine that ran over 4,200 meters underground in order to create the facility for Aperture Science, where they would expand their inventive and innovative pursuit beyond shower curtains.ĩ years later in 1956, Aperture signed a contract with the government to receive funding for their projects and to make and deliver shower curtains to branches of the United States military. Johnson ended up renaming the company to 'Aperture Science Innovators' in an attempt to make their products seem more hygienic and appealing to the consumers. However, then it was known as 'Aperture Fixtures', and was a shower curtain manufacturing company. Aperture was founded by Cave Johnson sometime in the early 1940s.
