About the Lab

Robert H.N. Ho
Robert H.N. Ho

The Ho Tung Visualization Laboratory was a special gift to Colgate from Robert H.N. Ho '56 in memory of his grandfather Sir Robert Ho Tung.

Knighted twice by King George V and Queen Elizabeth II, Sir Robert Ho Tung was active as a businessman and philanthropist in the British Crown Colony of Hong Kong. At the September 15, 2007 dedication ceremony for the visualization lab, Mr. Ho quoted a Chinese proverb: "huh shwei, suh yuan"-"Drink water: consider source."

May those who discover new frontiers in this laboratory consider how they can model Sir Robert Ho Tung and Robert H.N. Ho's inspiring words.
