BiographyHesse was born in 1850 in New York City to Gottfried Elishemius, a wealthy import merchant, and his wife, Ceclie Elise.[1] She met her husband and research partner Walther Hesse in 1872 while in Germany. They were engaged in 1873, and married in 1874 in Geneva.[3] Research contributionsHesse worked in an unpaid capacity to assist her husband through preparing bacterial growth media, cleaning equipment and producing illustrations for publications.[3] In 1881, while her husband was working in the laboratory of German physician and microbiologist Robert Koch, Hesse suggested that agar was preferable to gelatin for cultivating bacteria. She was aware of the properties of agar as a gelling agent that maintained its gel properties at warm temperatures through using it at home to make puddings and jellies. A neighbour who had lived in Java had introduced agar to her when she lived in America. This led to Koch using agar to cultivate the bacteria that cause tuberculosis.[3] Although Koch, in an 1882 paper on tuberculosis bacilli, mentioned he used agar instead of gelatin, he did not credit either Hesse, or mention why he made the switch. Hesse's suggestion never resulted in financial benefit for the Hesse family.[3] See also
