Jan Szczepanik (dob) was a Polish inventor, with several hundred patents and over 50 discoveries to his name, many of which are still applied today, especially in the motion picture industry, as well as in photography and television. Some of his concepts helped the future evolution of TV broadcasting, such as the telectroscope (an apparatus for distant reproduction of images and sound using electricity) or the wireless telegraph, which greatly affected the development of telecommunications.

Both his sons died in tragic accidents within a few months of each other, but Kuklinski did not discount the possibility that the KGB was behind it.

The Polish newspaper Trybuna lamented that "Colonel Ryszard Kukliński—a spy, deserter, and traitor—has been turned into a model of virtue and a national hero of the rightists." In a 1997 survey conducted by the CBOS, 27 percent of Poles considered Kukliński a hero and 24 percent a traitor (compared to 12 and 24 percent, respectively, in 1992.
