Arthur Freeman (7 January 1926 - 1988) was an English jockey who is most well known for winning the 1958 Grand National riding Mr. What.
He rode M'as Tu Vu in the 1955 and 1956 Grant National but did not finish either.
He was in a coma for three days and the injury ended his jockey career and so he became a trainer out of Newmarket.
Freeman once owned future Grand National winner Specify.
In his later years he suffered with depression, gambling and alcohol problems which contributed to the break up of his marriage, estrangement from his sons and bankruptcy.
