William Dermod O’Brien, Irish painter commonly known as Dermod O’Brien, dies in Dublin on October 3, 1945. Most of his paintings are landscapes and portraits. His work is part of the painting event in the art competition at the 1928 Summer Olympics in Amsterdam, Netherlands.

O’Brien is born on June 10, 1865 at Mount Trenchard House near Foynes in County Limerick, the son of Edward William O’Brien and Hon. Mary Spring Rice, granddaughter of Thomas Spring Rice, 1st Baron Monteagle of Brandon. For a time after his mother’s death, he is raised by his aunt Charlotte Grace O’Brien, along with his sisters, Nelly and Lucy. His father subsequently remarries in 1880. He is educated at Harrow School and Trinity College, Cambridge.

O’Brien marries Mabel Emmeline Smyly, daughter of Sir Philip Crampton Smyly, on March 8, 1902. Together they have five children. His son Brendan, a surgeon in Dublin, marries artist Kitty Wilmer O’Brien. His daughter Rosaleen Brigid becomes an artist, also known as Brigid Ganly after her marriage to Andrew Ganly. Another artistic relative is Geraldine O’Brien.

Unlike many of his Irish contemporaries, after graduating from Cambridge O’Brien does not study art in Dublin, opting instead to travel to Paris, where he studies the paintings at the Louvre. In 1887, he visits galleries in Italy and then enrolls at the Royal Academy of Fine Arts in Antwerp, Belgium. At the Academy he is a fellow student of Walter Osborne. He leaves Antwerp in 1891 and returns to Paris, where he studies at Académie Julian. He relocates to London in 1893 and then Dublin in 1901.

O’Brien is designated an associate of the Royal Hibernian Academy in 1906, a member in 1907, and is later president between 1910 and 1945. He is made an honorary member of the Royal Academy of Arts, London in 1912.

O’Brien holds the office of High Sheriff of County Limerick in 1916 and serves as Deputy Lieutenant of County Limerick. He serves in the Artists Rifles during World War I.
