[1][2][3] In 1900, before beginning her scientific education, Lebour began her research career with a paper on land and freshwater molluscs in Northumberland.

While studying for her master's degree, Lebour was on staff at Durham University.

After publishing these books, Lebour used the newly invented plunger jar to better study the egg and larval stages of krill in the North Atlantic, Antarctica, and Bermuda.

She also published well-regarded work on the eggs and larvae of sprat, herring, and pilchards.
