Mass., in 1932 and was carried out by
Harrison and Anderson who conlprised
the agency's authorities on fish oils.
When they were transferred to Seattle
in 1933, this work was continued. Eventually
a fairly extensive series of research
studies were carried out by Sanford
(1945); Sanford et al. (1946); Sanford
and Bonham (1947); and McKee et al.
(1944). This vitamin A in fish oil work
ceased in 1950 when synthetic vitamin
A became available. At least in the
United States, it was so much less expensive
to use the synthetic vitamin A
than to process fish livers that that industry
was no long feasible.
