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 than being engine divided.
