Livia Ruth Gollancz (25 May 1920 − 28 March 2018) was the first female principal horn of a major UK symphony orchestra.

Her early musical education had included learning the clarinet though she was more successful as a pianist and violinist later changing to the viola.

During her performing career she freelanced with many theatre and concert orchestras including The Old Vic Company and the Royal Opera House.

[5] The conductor and founder of The Proms Henry Wood heard Gollancz performing with the London Symphony Orchestra in May 1941 and was prompted to write to her the following day: "Dear Miss Gollancz, A year or two ago your father told me you were studying the horn and at yesterday's concert I had the pleasure of seeing you, particularly in the Brahms Second Piano Concerto.

May I offer you my warmest congratulations, your tone and phrasing in the solo passages allotted to the third horn rang out splendidly in the body of the hall – a real achievement for a woman artist – Bravo.

In 1945 Gollancz resigned from the Hallé due to her judging Barbirolli's approach to classical music as "too romantic for my taste".
