Knowles' career was interrupted by his service in both the First World War and the Second World War.

John Alder Knowles was granted an Honorary Master of Arts from the University of Hull in 1957 for his scholarly monograph on the York School of Glass Painting (published in 1936 and illustrated with his own sketches and photographs).

John Ward Knowles was born in 1838. He left school at the age of 12.

Following a visit to the Great Exhibition in London with his father in 1851, Knowles enrolled at the newly opened School of Design in York. He continued there as a pupil until 1854, winning prizes for his stained glass work in 1852 and 1854. In around 1858, Knowles moved to London for a year to work for Heaton and Butler, where he developed an interest in photography and architecture.

In 1863, following his return to York, Knowles began to undertake conservation work on the 'Fifteen Last Days of the World' window in All Saints Church. Three years later he was a member of the committee for the 1866 Great Exhibition at Bootham, York.

In 1869 Knowles moved his stained glass business from Goodramgate to Stonegate. Five years later he married Jane Annakin, with whom he had two sons, John Alder and Milward, and four daughters. Both sons would follow him into the family business of J W Knowles & Sons. In 1874 he also bought and began to restore 23 Stonegate (now number 35).

During the 1880s and 1890s Knowles undertook extensive conservation work on the St Cuthbert and St William windows at York Minster, during which process he photographed all the panels before their restoration and rearrangement. He also spent some time working on the stately home Nostell Priory.
