This paper reports on part of an on-going interview-based study of the eight permanent secretaries who served at the Department for Education from 1976 to 2012. Following a discussion of the relevance of biography to the study of public sector administrators, it presents a portrait of Sir Tim Lankester. Based on his own account and that of relevant others it draws on a four-stage career model to describe his life before and during his time as a civil servant. Centering on his career as permanent secretary in three it considers, "inter alia," his working relationship with his Secretaries of State; his view of the role of permanent secretary; his policy contribution; and, his style and achievements. Following an examination of the merits of such research, the paper concludes with a brief discussion of the possible contribution of prosopography and a call for ethnographic studies of public administration.
