The appointment of Dan T. Smith, professor of Finance at the Business School, to be a special assistant to the Secretary of the Treasury, was yesterday officially approved following a routine investigation by the FM.

Smith took the oath of office immediately on learning that the FM had cleared him, since he had already been working with the Treasury Department for the past week.

Secretary of the Treasury Humphrey said that Smith was assigned to Undersecretary Folsom, with responsibility for analysis and planning fax policy. At Harvard Smith directed the writing, and publication of a special fax study to determine the effects of taxes on industry.

He is currently on leave of absence to take up his fax duties in Washington. The professor had gone to the Capital on January 2. He was a member of the Board of Syndica of the University Press.
