Wostinholm was a charted accountant, stockbroker and estate agent who worked out of offices on Bramall Lane in Sheffield.^[1] He took the position of secretary of the Bramall Lane Cricket Ground in 1862 and was responsible for the ground's development into a top class cricket venue. He also became secretary of the recently formed Yorkshire County Cricket Club and worked to establish Yorkshire as the leading county.^[1]

In 1889 he was instrumental in the formation of a new football team to play at the Bramall Lane ground during the winter months and became the club secretary of Sheffield United at their inception.^[1] Although the team was selected by a committee and coached by a trainer, Wostinholm undertook many of the duties currently associated with that of a football manager including player transfers and dealing with The Football Association.
