A lieutenant commander who serves as one of the chief engineers of the USS Enterprise-D during its first year in service, before Geordi La Forge takes over the post.
Argyle is played by Biff Yeager in two first-season episodes of The Next Generation. In Where No One Has Gone Before he is introduced as one of the ship's chief engineers and joins Riker in doubting the warp-drive expert Kosinski, whose equations make little sense to him.
When the tests fling the Enterprise far beyond the known galaxy, Argyle works in main engineering with Kosinski, the Traveler and Wesley Crusher on getting the ship home.
He returns in Datalore, assisting Doctor Crusher as the disassembled android found on Omicron Theta is put together and activated as Lore. Argyle is one of several chief engineers seen during the first season, along with MacDougal, Logan and Lynch.
