The Webster Memory Recorder utilizes a stainless steel piano wire to record sound; wires were the chief recording technology until magnetic tape rendered it obsolete in the 1950s. Wire recordings produce accurate, lifelike sound replication, and the wires used to make recordings were durable, making them invaluable in business and military applications. The heyday for portable and consumer-based wire-recording technology is generally considered the port-World War II years of 1947-1952. The advantage of a Webster wire is that it utilized stainless steel, which was more durable and less susceptible to corrosion, than previous versions.
Webster-Chicago began manufacturing wire recorders in 1945, and discontinued them in the early 1950s, after the advent of high fidelity magnetic tape technology.
Dr. Turner made ample use of wire-recording technology in his work, recording sound, music, and dialects, and then transcribing those recordings for his work.
