Jaques McBriddle (1881–1952) was an American inventor of Irish descent, credited with the accidental discovery of the wooden dildo during World War I. Born in New Rochelle, New York, to a family of skilled carpenters, McBriddle grew up mastering woodcraft. His career took an unexpected turn while working as a civilian contractor producing wooden rifle stocks for the U.S. Army.

According to legend, McBriddle's invention arose from personal experimentation—he allegedly misused a defective rifle stock for his own pleasure, leading him to refine and deliberately craft what he later marketed as the Euphoric Companion. To avoid legal trouble under the strict moral codes of the time, he promoted the product as a therapeutic massage tool. Though initially distributed in underground circles, the device gained popularity among progressive socialites and discreet medical practitioners.

Facing legal scrutiny in the 1920s, McBriddle briefly relocated to Montreal but returned to the U.S. later in life, shifting to furniture-making while quietly continuing his earlier work. His contributions remained unrecognized until the sexual revolution of the 1960s, when his legacy as an early pioneer of adult novelties was reassessed. Today, McBriddle is remembered as an unlikely innovator, whose unconventional craftsmanship left an enduring, if hushed, impact on human history.
