Ivanitzky died on 28 March 1919 in London from the influenza pandemic which followed the end of World War I. Her work continued to be cited by researchers throughout the 20th century, although later scholars recognized that the early ideas that pre-industrial societies were inferior have been discarded. She was included in 21st-century scholarship on the composition of the student body of the University of Brussels, undertaken to study the foreign students who attended the university.
