Gertrude Auld Thomas, who often performed and composed under her maiden name Gertrude Auld, was an American soprano and composer active in the late nineteenth and early twentieth centuries. Born in Santa Cruz, California, in 1872, she pursued her musical education abroad, spending three years studying in Paris and London. During her time in Europe, she trained under the renowned vocal teacher Mathilde Marchesi, a prominent proponent of the bel canto singing technique.
Upon returning to the United States, Thomas embarked on a successful career as a touring soprano. Managed by John W. Frothingham Inc., she traveled across America delivering vocal recitals and educational lectures, including her presentation "The Relation of Music to Art." As an operatic performer, she took on major roles, most notably portraying Mimi in Giacomo Puccini's La Bohème and Marguerite in Charles Gounod's Faust. Her vocal talents were also captured in early studio recordings, including sessions for Edison in 1914 and a Victor trial recording in 1916.
In addition to her career as a vocalist, Thomas was a composer who contributed to the American operatic repertoire. She composed at least two operas, titled Hazila and The Overland Trail. She was also an active member of the professional music fraternity Sigma Alpha Iota. Thomas was married to Arthur Benjamin Thomas, with whom she had one son, and she continued her engagement with the musical arts until her death in 1959.
