Data mostly from Wikipedia, but, surprisingly, the Daily Mail had an
interesting article:
<
http://www.dailymail.co.uk/sport/tennis/article-4701622/Roger-Federer-not-oldest-Grand-Slam-winner.html?ITO=1490&ns_mchannel=rss&ns_campaign=1490>
That article ignores anyone before the Open Era - three players were
older than Muscles, Bill Larned in 1911 (38), Arthur Gore in 1908 & 09
(40 & 41) & Andre Vacherot in 1901 (41). Vacherot being the oldest.
