Deletion of Robert Kyp

Comment: to Carbon-filament bulb, which in a section called 'Resurgence' names someone who started selling these bulbs in the 1980s, but does not mention Robert Kyp who starting manufacturing them in 1964. The ''Chicago Tribune'' source is good, but I can't find anything else besides 2 paras in a 1989 Associated Press article "Right Use of Period Light Fixtures" https://www.newspapers.com/image/405583208/?terms=%22Robert%2BKyp%22, and a 2001 article in ''The Houston Herald'' about a firm called JLD Inc., which took over the manufacture of the bulbs after Kyp closed up (and in which Kyp had a 25% interest) https://www.newspapers.com/image/178695935/?terms=%22Kyp-Go%22. I don't think that's quite enough to meet  - although there is certainly more information in all three sources which could be added to this article
