Dr Marie Victoire Lebour

Thanks to the work of Northumbrian native Dr Marie Lebour (1876-1971), we now have an unprecedented view into the life of our seas. An expert on crustaceans, molluscs and microplankton, her books and research papers are still in use by scientists and students today.

Driven by curiosity, and before she had any scientific training, Lebour first published on molluscs and their parasites in 1900. She continued her investigations on parasites as a Zoology student at Durham University, and later in the 1930s she resumed her studies on molluscs as an established researcher at the Marine Biological Association’s Plymouth Laboratory.

Lebour studied the life cycles of many aquatic organisms, rearing them from eggs to larvae and on through metamorphosis to the adult, using the newly invented plunger jars which kept water flowing and full of oxygen. Her knowledge has contributed to our understanding of marine dwelling organisms from herring fish to single-cell diatoms.

The illustrations in her research papers showcase her artistic talent, which she had developed as an art student before her transfer to a career in science.

Illustration from Dr Marie Lebour’s paper: Larval and Post-larval Lima from Plymouth. Journal of the Marine Biological Association of the United Kingdom, 21(2), 705-710.

Lima are salt water clams and their shelled larva are called veliger.

A – E show larval growth from 0.08 mm to 0.32 mm. G,H,J,K are post-larva undergoing metamorphosis to young clams.
