For the early electrolysis engineers who were miti- gating corrosion 80 to 100 years ago, today's range of corrosion-control equipment avail- able for the modern corrosion professional surely would have been unimaginable. Editor's Note: Mark Lewis is the unofficial curator of EBMUD's antique corrosion test equipment and instrumentation collection, which was on display during CORROSION 2013 in Orlando, Florida, USA from March 18 to 21 in the Exhibit Hall. The collection, generously on loan from EBMUD, is cur- rently on display at NACE Interna tional's Elcometer Building in Houston, Texas, USA. Bibliography Lewis, M.
