A. B Wolfe was a slightly peripheral member of the institutionalist group in the 1920's contributing to the Tugwell volume and to other volumes dealing with the relationships between the social sciences. He had a particular interest in economics and philosophy, ethics, and in scientific method. He later shifted his work almost entirely to demography. I do not know much about this aspect of his work but I remember hearing a paper on it by a young scholar at an HES meeting a few years ago. If I remember correctly Mary Morgan was also at that session--she may have been chairing it. Malcolm Rutherford.
