"Alfred" Gilbert (aka A. C. Gilbert) was the co-winner in the pole vault (with another American, Edward Cook) in the Olympic Games of 1908 in London (3.71m). As Ed Grant had implied, it is a bit difficult to imagine that Jason Alexander's television character had once achieved such athletic prowess. However, Alexander portrayed the role admirably and I enjoyed the movie. There is more on A.C. Gilbert at www.frontiernet.net/~davegilbert/acg/ and pubs.acs.org/hotartcl/tcaw/00/sep/schmidt.html/.
