Pickett was an American manufacturer of slide rules characterized by all metal construction. The founders, Roswell Colvert Pickett and Arthur F. Eckel started out making all-metal slide rules in 1944 using magnesium and later evolved to aluminum as aluminum alloys became more machinable. Pickett slide rules were chosen to be used by the Apollo astronauts on their mission to the moon, as they were lighter than their wood core counter parts. Picket used a photo print on their slide rules, rather trhan being engine divided.

Picketts are remembered by many later-day alumni for their characteristic yellow 'eye saver' color. Pickett also produced all-plastic low-end slide rules in the waning days of the their life. When the company folded with the rest of the industry, the slide rules were going to be sold as scrap metal to Mexico, but were rescued by Dick Schwartzer and later sold to collectors over the last 25 years. There are thousands of the plastic Pickett models hiding in warehouses waiting to be slowly feed into the collector market.
