We are very sad to announce that Professor Bill Webber passed away on November 28, 2018. Bill remained keenly interested in his research of the Voyager mission data to the last moments in his life and continued to publish papers as recent as in August. Bill and his wife Barbara also contributed generously to the Department through funding the William Webber Voyager Graduate Fellowship. We will miss him dearly. A detailed obituary will be published at a later date.
