Henri Bernard Beer (born April 7, 1909 in Amsterdam, died 1994) was a Dutch inventor and business man.
[2] Henri Beer was working from 1957 to 1972 at the company Magneto Chemie (since 2002, Magneto Special Anodes, in The Netherlands),[3][4] where he investigated the possibilities of coating titanium with a precious metal or precious metal oxide; he found this could be used to replace graphite in a chlor-alkali cell.
Almost simultaneously, but independently, J.B. Cotton's group in the Metals Division of ICI filed a patent on platinum electrodeposited onto titanium.
The next step was moving from platinum electroplated titanium to platinum-iridium mixtures applied using the paint-thermal decomposition method.
In 1967, the Beer 2[8] patent followed, which covered the optimal, stabilized ruthenium-titanium oxide mixture (RuO2/TiO2) for chlorine evolution in the chlor-alkali process.
