Described by
Time magazine as a 'brash, engaging young Briton', he exhibited widely throughout North America during his time at Brown University and thereafter, including in Boston, Manhattan, Providence, Chicago, Toronto, San Francisco and Los Angeles. He remained resident in the United States, painting in a former Methodist chapel in
New Hamburg, New York. Hancock mainly worked in watercolour and his art was both
modernist and distinguished by a strong interest in engineering and technology. He concentrated on urban landscapes, trying to capture what he called the 'visual language that technology uses to create the city environment'. He was an official artist to
NASA and its
Apollo space programme in the 1960s as part of the
NASA Art Program. He later undertook commissions for the
United States Navy, including journeys at sea on
Polaris nuclear submarines. His work can be found in the
Smithsonian American Art Museum, the
National Air and Space Museum in Washington, D.C., the
United States Navy Art Collection, the
Air Force Space & Missile Museum, the
High Museum of Art in Atlanta,
Agnes Scott College in Georgia and the University of Texas at Galveston among others. Another piece was owned by British Prime Minister
Winston Churchill. == References ==
