In his 1842 paper Bennett gave the earliest description of pulmonary aspergillosis. Bennett was one of the first to recognise the importance of the microscope in the clinical investigation of disease and his use of the instrument was central to identifying the presence of a fungus in the sputum and, post mortem, lungs of the patient with aspergillosis.
