Ethel Jenner Rosenberg (6 August 1858 – 17 November 1930) became the first English Baháʼí.
Rosenberg was born in the city of Bath, Somerset, to a Jewish family and was a painter trained at the Slade School of Fine Art in London.
Rosenberg traveled to America three times, initially doing so with Mírzá Abu'l-Faḍl and Laura Clifford Barney.
When she arrived in Haifa for her third pilgrimage, in 1921, she found that ʻAbdu'l-Bahá had recently died.
Shoghi Effendi gave her instructions for the calling of the first National Spiritual Assembly of England, on which she would serve.
