Which statement about Robert Schumann is NOT true?

The statement that Robert Schumann had the longest career of any Romantic era composer is not true. While Schumann is indeed a significant figure in Romantic music, his career was notably shorter than that of many of his contemporaries, such as Franz Liszt or Richard Wagner. Schumann’s life was marked by struggles with mental health, which ultimately led to his early death. His contributions to both piano and vocal music, as well as his role as a music critic, highlight his impact on the music world during the Romantic period. However, the longevity of his career does not match that of other prominent composers of the era.
