Michael Browne obtained his BA (1958) and M.Sc. (1965) degrees from the University of the Witwatersrand and his Ph. D. (1969) from the University of South Africa. He was employed at the South African National Institute for Personnel Research from 1959 to 1973, starting as Research Assistant and ending as Chief Research Officer. While at the NIPR he spent several years on sabbatical in the USA. In 1963 he was invited by Rolf Bargmann to spend six months with him at the IBM Research Center in Yorktown Heights, N.Y. At the time Rolf was manager of the Applied Statistics group of the IBM Research Center and was a dedicated professor with no students. He gave Michael a desk in his own office and sporadically in response to questions he would go to the chalk board and deliver a lecture on some aspect of statistics or psychometrics. The foundations for Michael’s subsequent career were laid during this visit. Not only did he gain a great deal of foundational knowledge but his attitudes were strongly influenced by Rolf’s insistence on perfection and impatience with anything that was not up to standard. Another influential period of his life was three years spent as one of Fred Lord’s Visiting Research Fellows in 1967, 1968 and 1973. Members of this group at various times during Michael’s visits were Bob Jennrich, Karl Jöreskog, Walter Kristof, Fumiko Samejima, Bill Meredith, Mel Novick, Peter Schönemann, Ingram Olkin, and Leon Gleser. All were persons who already had, or would subsequently achieve, international prominence in psychometrics. Michael attributes the development of his abilities more to early interactions with very capable persons around him, than to formal classroom lectures. After his last visit to ETS he joined the University of South Africa and is now at the Ohio State University.

Michael Browne's research has been primarily concerned with statistical modeling of multivariate psychological data. He has made contributions on asymptotically distribution free estimation in the analysis of moment structures, asymptotic robustness of multivariate normal theory against violation of assumptions, multiplicative models for multitrait-multimethod data, circumplex models for the investigating the personality circle, nonlinear latent curve models, and rotational methodology for factor analysis. His main current interests are in multivariate time series and dynamic factor analysis. He regards his collaborations with Stephen du Toit, Alexander Shapiro, Bud MacCallum and John Nesselroade as highlights of his later academic career.
