The first Canadian General, Wiseman was born in 1907 and was commissioned as a Salvation Army officer in 1927. He served variously in pastoral, editorial, military chaplaincy, missionary, training and administrative positions in Canada, the United Kingdom and Africa.
Wiseman was elected the 10th General on 13 May 1974 and assumed command on 6 July. Due to retirement age, Wiseman served for three years (less two days), a shorter term than any of his predecessors. He had been nominated as a candidate for the Generalship at the 1969 High Council but had felt led to withdraw it.
The General's evangelical zeal and concern for The Salvation Army's work in many third-world countries - where people faced disease, famine and poverty - led to advanced training for potential leaders from Asia and Africa in 1976.
Wiseman retired in 1977 and died in 1985, aged 78.
