Road 1 North Path C1 Site 1 East

Media magnate, politician and philanthropist

John Langdon Bonython joined the Advertiser at the age of 16, initially as a reporter. He steadily worked his way up the ranks until he made Editor at the age of 36; a position he held until his retirement at age 81.

Bonython became very wealthy through successful speculation in mining. This allowed him to purchase the Advertiser in 1893, making him both Editor and sole proprietor. He became a very influential figure. Under Bonython’s leadership, the Advertiser grew to be South Australia’s most prominent daily newspaper.

Bonython was also a supporter of the Federation movement, and used his influence to popularise Federation, safeguard the rights of the smaller states, and promote the interests of South Australian business.

In 1901 he was elected to the House of Representatives in the first Federal Parliament, retiring from politics in 1906.

Throughout his life, Bonython donated large sums to several causes. His largest single donation was £100,000 towards the completion of Parliament House in 1934.

On his death he was one of Australia’s richest men.
