A view from the 1899-1900 Siboga expedition

Discovering Ocean Life

Anna loved plants and animals from a young age. Her interest grew with regular visits to the Amsterdam zoo. In 1880, she started studying at the University of Amsterdam. At that time, women often had to work separately from men. So, Anna did her lab work in a different room.

The Siboga Expedition

One of Anna's most important adventures was the Siboga Expedition. This journey was super important for studying ocean algae in the western Pacific. She traveled with her husband, Max Weber, who was also a scientist.

During this trip, Anna found many new types of algae. She even discovered whole new groups, called genera, of algae. Some of these new groups included Periphykon, Exophyllum, and Microphyllum.

Anna wrote down many of her discoveries from this expedition. She published a detailed book called Corallinaceae in 1904. She also wrote a four-part series called Liste des algues du Siboga between 1913 and 1928.

Earlier Discoveries

Before the Siboga Expedition, Anna went on other trips. She explored northern Norway and the East Indies. On these trips, she found the algae group Phytophysa. She also discovered how some algae live together with sponges in a special way called symbiosis.

Later Work and Life

Later in her life, Anna worked from her small home lab in Huis Eerbeek. Many other botanists would visit her there to ask for advice. Besides her work with marine biology, Anna also helped with child-care centers in Amsterdam.

Anna received several awards for her amazing work. She got one of the highest honors in her country, the Chevalier de l'ordre d'Orange-Nassau. She also received an honorary doctorate degree from the University of Utrecht. A bird species, the Dicaeum annae, was named after her to honor her contributions. Anna passed away on October 29, 1942, when she was 90 years old.
