Agnes Smith Lewis and Margaret Dunlop Gibson

Agnes Smith Lewis (1843–1926) and Margaret Dunlop Gibson (1843–1920), nées Smith (sometimes referred to as the Westminster Sisters), were English Semitic scholars and travellers. As the twin daughters of John Smith of Irvine, Ayrshire, Scotland, they learned more than 12 languages between them, specialising in Arabic, Christian Palestinian Aramaic, and Syriac, and became acclaimed scholars in their academic fields, and benefactors to the Presbyterian Church of England, especially to Westminster College, Cambridge.
