Sidney Samuel Lenz (1873 - 1960) was an author and champion player all forms of bridge and bridge. Lenz was also expert in many other games and sports but is perhaps best known for his participation in the famous 1930 Culbertson-Lenz match. Lenz wrote several books on auction and contract bridge and "Lenz on Bridge" (1926) is ranked as a classic.
