Phil Zimmermann (Figure 8.1) was born in 1954 and raised in Florida. His interest in codes began at an early age. For instance, in the fourth grade, he was deciphering some minor codes broadcast on children’s television shows. He began reading about codes, and steganography, even creating his own invisible ink out of lemon juice, as well as some of his own original ciphers. This interest continued through his youth, so that by the time he entered Florida Atlantic University in 1972, he turned to computers as a tool for the cryptographic skills that he, independently, had honed over the years.
