The most famous scene of machine death in film — HAL 9000 singing "Daisy Bell" ever
more slowly as astronaut Dave Bowman disconnects its memory in *2001: A Space Odyssey*
(1968) — has a documented real-world source. **Arthur C. Clarke** visited his friend
**John Pierce** at Bell Telephone Laboratories and, per the Library of Congress essay,
"took special note of this singing and talking computer." He later scripted it into
HAL's shutdown, where the AI "sings 'Daisy Bell' as power ebbs out of his circuits."

The scene is therefore a near-direct transcription of the
[[claim-1961-daisy-bell-first-synthesized-computer-song|1961 Bell Labs demonstration]]
in which Max Mathews, John Kelly, and Carol Lochbaum first made a computer sing. What
began as a lighthearted engineering party trick — a Victorian bicycle-duty pun sung by
an IBM 704 — acquired its ominous meaning only when a novelist standing in the hallway
carried it into fiction seven years later. The bridge from lab to legend is a single
visitor's memory, not any property of the machine or the song itself.

The same demo's central figure, Mathews, is the namesake of the visual programming
language [[claim-max-msp-named-after-max-mathews|Max]], closing a loop back to the
[[claim-labview-max-independent-patch-cord-convergence|LabVIEW/Max dataflow]] thread.
