Ardelle Glaze: recording wire, then the wire inside the body

1910–1985 · THE MATERIALS INVENTOR

The wire: The Business section holds the corporate record of Fort Wayne Metals — Ardelle Glaze (1910–1985) founding it in 1946 to make magnetic recording wire — including Scott Glaze's figure that within five years the company was making 80 percent of the recording wire used in America. This entry holds the inventive content, from the company's own research director's account as preserved by Haines. Glaze's ECHO wire was the dominant magnetic recording medium of the 1950s. His second act began when the company turned to medicine: access wires for the heart kept fracturing, and Glaze's solution was materials, not mechanism — a clean vacuum-melted stainless steel, drawn to an extremely smooth finish so it would not stress and break inside the body. The Fort Wayne Metals Research Products line followed in 1970, and today more than ninety percent of the company's materials end up in the human body, in the company's own figure. The record's precision is kept here too: nitinol, the shape-memory alloy the company works in, was not invented in Fort Wayne — it was discovered at the U.S. Naval Ordnance Laboratory in 1958–59 — but Fort Wayne Metals adapted it, and in June 2023 the company announced its nitinol mesh work with NASA's Glenn Research Center toward airless tires for lunar rovers, technology with Mars in view. Glaze's kind of breakthrough rarely gets a plaque: it is the alloy and the finish, the difference between a device that fails in a patient and one that does not.
