The NEXTGEN Cassava family lost Martha Hamblin on March 15, 2015 to ocular melanoma.
Martha once said that for all her years working in science, it hadn't amounted to "a hill of beans" when it came to the betterment of human welfare. But she was wrong: her last scientific project is "amounting"--to a hill of cassava. Martha essentially wrote and shepherded to approval the NEXTGEN Cassava Breeding Project. Even after receiving her diagnosis, she kept involved in the project's scientific work and kept tabs on essentially all of its components, ensuring that nothing fell between the cracks. In addition, her consistently perceptive insights and seemingly magical clearing of the tangled undergrowth of scientific writing were an invaluable help to the other researchers. Her impact on this project will be felt for years to come.
