Kate Fanny Loder, later known as Lady Thompson, was born on 21 August 1825 in Bath, Somerset. She came from a musical family; her father, George Loder, was a flautist, and her mother was likely a piano teacher. Kate showed great talent from a young age and studied at the Royal Academy of Music in London. At just 17, she made her public debut performing Mendelssohn’s G minor piano concerto. In 1844, she made history as the first female professor of harmony at the Royal Academy.

On 16 December 1851, Kate married Henry Thompson, a prominent surgeon, and eventually stepped back from public performances. Despite this, she continued to compose music and taught many students, including the notable artist Sarah Louisa Kilpack. They had three children: Kate, Henry, and Helen.

In her later years, Kate experienced health issues but remained passionate about music. She passed away on 30 August 1904. In 1871, she hosted the first British performance of Brahms’ German Requiem at her home, showcasing her lasting influence on music.
