Whose wife as a biblical figure turned into a pillar of salt?

Lot's wife is a figure first mentioned in Genesis 19. The Book of Genesis describes how she became a pillar of salt after she looked back at Sodom. In the tale, Lot, Abraham’s nephew, lived in Sodom with his family. When two angels came into town, Lot invited them to stay with his family. After sharing the evening, the angels made sure Lot, his wife, and his two daughters left before God destroyed the city.

As they fled, the angels warned them, “Escape for your life! Do not look behind you, and do not stay anywhere in the valley; escape to the mountains, or you will be swept away." Lot's wife lagged behind him, looked back, and she became a pillar of salt. God’s warning was disobeyed, and so Lot's wife died.
