Emma Jane Greenland (after marriage, Hooker; 1760/61 – 9 September 1838) was an English painter, writer and singer.
In order to perfect her work, she moved to Italy and in 1783, in Rome, began studying encaustic painting with Joseph Pignatelli.
In 1785, in Florence, she practiced encaustic painting at the salon of Irene Parenti Duclos and thanks to her, Hooker began to attend the Royal Gallery.
She returned to London in 1786, and in the following year, published Curios discovery of the ancient grecian method of painting on wax.
Greenland's music career gave her great satisfaction as when Johann Christian Bach dedicated to her six sonatas for piano and violin.
