The first scientist to think seriously of this potential was Vannevar Bush. In his 1945 article "As We May Think," he outlined "a future device for individual use, which is a sort of mechanized private file and library." Before the ENIAC was completed, Bush was already contemplating how information technology could enhance the individual's capability for creative thought. "The human mindÉ operates by association," Bush observed. The device that he proposed, which he named the Memex, enabled the associative indexing of information, so that the reader's trail of association would be saved inside the machine, available for reference at a later date. This prefigured the notion of the hyperlink. While Bush never actually built the Memex, and while his description of it relied on technology that predated digital information storage, his ideas had a profound influence on the evolution of the personal computer.
