John O'Brien died prematurely at just 53 years of age. During his life, he sustained a remarkable and enduring love of life, with an eye for beauty which he expressed so vividly in his varied artwork.

John studied at the prestigious Art Student's League in New York, where he later set-up one of three studios, the others being in San Francisco and Paris. His eye for beauty is seen in every painting; the interiors and exteriors are wholly imaginary, enticing and inviting the viewer to "wish they were there". His paintings are in private collections in Europe and the United States. His commissions included murals, portraits, and illustrations in addition to his highly successful series of romantic interiors.

Also reflected in his paintings is his passion for France, Italy, and Ireland from whence came the inspiration for his Eurpoean street scenes, neighbourhood cafes and cosy pubs. He created a unique style, which has come to be nown as "contemporary romantic realism". Many of his paintings have been appreciated worldwide as jigsaw puzzles. The beautifully detailed settings have appeared in over 20 different publications, and are firm favorite amongst puzzlers and collectors.

After being diagnosed with malignant melanoma in Spring 2004, John continued to paint and teach until the disease and treatment made it too difficult for him to continue. He was a devoted and loving husband and father to his wife Martha and daughters Michelle and Claire who often posed for his beautiful paintings.
