The use of an optimization program on a large computer for the design of lenses is a very recent phenomenon. Prior to about 1930 all lenses were designed by logarithms, and from 1930 to about 1960 they were designed by hand with the aid of a mechanical desk calculator and a book of sine tables. It is the purpose of this paper to indicate the kind of procedure that used to be followed when lenses were designed in this way. A numerical example is included to illustrate the process.
