The First Double Switch?

Dave Smith at Retrosheet had an interesting post on SABR-L I thought was worth sharing (not that all of his other members posts aren't of course). Anyway, someone asked a question about double-switches and he responded that a few years ago someone did some research on this question and the earliest use of the double-switch came on May 18 and May 21st 1955 and were done by the Orioles and their manager Paul Richards. Note that this simply the first one that can be found and so is not necessarily the final word.

The original poster noted that a double-switch was described in communication by the league office in 1973 but did not describe it as a "double-switch".
