Jane Squire

Jane Squire (bap. 1686 – 1743) was an English mathematician who was the only known woman to have participated openly in the 18th-century debates and discussions over the solution to finding longitude at sea. She was one of only two (the other being Elizabeth Johnson) who submitted schemes with the aim of receiving a reward (up to £20,000) under the 1714 Longitude Act. This work was especially important during the 18th century, when the British Empire depended heavily on the sea for trade, travel, and governing colonies.
