Bob Martin's records have been entered at listsofjohn.com (LOJ). You can see what he climbed here:
http://listsofjohn.com/CompletionAll.php?M=Bob+Martin
He did not finish all of the CO 11ers, but also climbed many lower peaks.
You can look up the peaks climbed for anyone who uses LOJ here:

Mike Garratt, Bob Packard, Mark Nicholls also have huge peak counts. Garratt is close to finishing the CO 11ers and 10ers and has climbed many lower peaks as well. Ken Nolan is just in the process of adding his peaks to LOJ, but is also close to finishing the CO 11ers.
The Contiguous US 14ers list is a can of worms. The peaks that make the list have varied too much over the years. A number of people have finished the list as it existed at the time they finished.
The problem comes from the concept of "rank." In most of the western US, a peak is considered ranked if it has 300 ft of prominence. This standard has been around for many decades in CO and has spread to other states.
CA has 12 ranked 14ers, but 15 "traditional" 14ers. Polemonium, Thunderbolt, and Starlight are "traditional" but not ranked.
CO is slightly more complicated. There are 53 ranked 14ers. That includes Challenger, which was named more recently than the others and thus was not included on the "traditional" list. The 54 "traditional" 14ers include North Maroon and El Diente, which are not actually ranked. Most people who claim to have climbed all of CO's 14ers since the time that Challenger was named and the concept of rank was understood would make sure they climb all 55 peaks covered by the ranked + traditional list. However, in earlier years, people would have claimed to have climbed all the CO 14ers after completing just the traditional 54.
A list of people who have submitted their names to the Colorado Mountain Club as having finished the CO 14ers (without any way of knowing which version of the list they finished) can be found here:
http://www.cmc.org/infopages/14ers%20Master_Nov2008.pdf
Scrolling to the bottom reveals 1346 names as of last Fall. There are undoubtedly many more people who have finished but don't know that the CMC keeps these records and that they can submit their names.
The list of 14ers in WA is the most problematic component in trying to list the 14ers of the Contiguous US. Rainier's high point is Columbia Crest. However, Liberty Cap has almost 500 ft of prominence and is thus also ranked. By standards in common use today, a list of ranked 14ers in the Contiguous US includes 2 peaks in WA -- Columbia Crest and Liberty Cap. Others still don't consider Liberty Cap a separate peak. The number of people who have completed all the Contiguous 14ers before Liberty Cap was included is larger than the number of people who have completed the version of the list that includes Liberty Cap. Some of the people who have climbed all of the 67 ranked 14ers in the Contiguous US have not climbed the 3 hard unranked CA 14ers -- including me. That diminishes the accomplishment in some people's minds, including my own.
The link given above by sarah.simon to Brian Kalet's list here on SP shows both the ranked and unranked Contiguous US 14ers. Ranked 14ers have a number in the "Rank" column and unranked 14ers don't.
