Obituaries of Society members are published as tributes and for future historians of science. The Vice-Chair of the Historical Astronomy Division (HAD) of the AAS is responsible for commissioning and compiling the obituaries. We depend entirely on the network of astronomical colleagues, including astronomy department and observatory administrators, for notification when an astronomer has died. Please contact the HAD Vice-Chair to announce the passing of a colleague or to volunteer to participate in the writing of an obituary. The HAD also maintains a list of needed obituaries.
