Pickett & Eckel, Inc.

Printer Roswell Colvert Pickett founded Pickett in Chicago in 1943 and was joined the same year by Arthur F. Eckel; the company's name changed to Pickett & Eckel. The "Eckel" was dropped from the company's slide rules (but not the official company name) around 1950. At about the same time, Keuffel & Esser sued Pickett & Eckel for copyright infringement. The company moved to Santa Barbara, California in 1964. That same year, the Pickett family sold the company to Times Mirror Co.; the name changed to Pickett Industries. Pickett Industries moved to Nogales, Mexico in 1979, by which time the company had stopped manufacturing slide rules. In 1985 it was again sold, this time to Chartpak.

A late entry into the US slide rule market, Pickett (or Pickett & Eckel as they were first known) quickly distinguished themselves with their high quality aluminum designs. Well-known for their "eye-saver" yellow surfaces (see below), Pickett was a popular favourite among American slide rule users.
