What is NOT true about Clara Wieck Schumann (1819-1896)?

The assertion that Clara Wieck Schumann achieved fame in the latter years of her life is not true. While she was indeed a renowned pianist from a young age and gained significant recognition during her prime musical years, it can be said that her fame was established early in her career rather than exclusively in her later years.

Clara Schumann was a child prodigy, performing extensively across Europe, which contributed to her early fame. Although her recognition may have continued throughout her life, particularly as a figure in music after her husband's death, her most significant achievements and acclaim as a performer and composer came during her youth and middle years.

The other statements accurately reflect her life and circumstances. She was celebrated as a pianist almost from childhood, was a respected composer, and faced personal and professional challenges, including those arising from her husband Robert Schumann's struggles with mental health, which impacted her career and personal life.
