Edward Westbrook Veitch (4 November 1924 – 23 December 2013[1]) was an American computer scientist.
In his 1952 paper "A Chart Method for Simplifying Truth Functions",[2] Veitch described a graphical procedure for the optimization of logic circuits, which is referred to as Veitch chart.
Depicting a multi-dimensional cube on a flat diagram that makes it easy to see these relationships: In a last minute change before his presentation Veitch removed the spacing between the 2×2 cell groups.
This was a poor decision because it made it more difficult for the user to grasp the overall structure of the function, as well as the rules Veitch used in recognizing simplifications.
In his last years before his death in 2013,[1] Veitch learned from solving Sudoku puzzles that spaces or heavy lines between groups of boxes can be very helpful especially if one has poor eyesight, such as Veitch had.
