4.11 Pickett, USA

The Pickett Company (originally Pickett and Eckel) began in Chicago right after World War II. Their original slide rules in 1944 used magnesium to obtain a lighter rule. However these rules had trouble with humidity and often became difficult to slide. Pickett began using aluminum alloys around 1950 and became a very popular brand in the United States. The “Eye-Saver” (ES) rules have a characteristic yellow color, but white counterparts (T) were still maintained as well.

The Pickett slide rule was a popular choice for space flight during the U.S. space missions leading up to and including the moon landings. See the short vignette Rules to the Moon.
