Agnes Gavin (1872–1947), was an Australian actor and screenwriter in the silent film era. She worked in collaboration with her husband John Gavin throughout her career. She wrote the majority of his films and was arguably the first specialist screenwriter in the history of the Australian film industry. In newspapers she was advertised as the "well known picture dramatizer" and was praised for creating "cleverly constructed stories". Many of her films are considered lost.
She was born in Sydney as Agnes Adele Wangenheim. At the age of eighteen she married Barnett Kurtz, and became Agnes Kurtz. Barnett Kurtz had attempted to divorce Agnes in March 1897. Kurtz read a letter to the court in which Agnes said she wanted a divorce; Agnes said she did not want to divorce and wrote the letter just to annoy her husband; the divorce was not granted. In December 1897 Agnes sued for the divorce on the grounds of adultery by her husband and it was granted. Their divorce was highly publicized.
On October 3, 1898, Agnes married stage actor John Gavin, and for many years they worked together in Vaudeville and Bland Holt's stage company.
In 1904, Agnes Gavin was accused of abusing her neighbor with violent language, as well as menacing her with a hammer and threatening to chop down her door with an ax. The court ordered her bound to the peace for six months.
In her first marriage she had a daughter named Isadore, who died on September 12, 1917. John Gavin died in 1938 and Agnes followed in 1947. The couple is survived by two daughters and several grandchildren.
In 1910, Gavin and her husband made their first film together, Thunderbolt, produced by H. A. Forsyth. John Gavin played the main character.In their next film with Forsyth, Moonlite, Gavin played an aboriginal girl named Bunda Bunda while wearing blackface.
Agnes Gavin then went on to write several films for Crick and Finlay, which her husband directed.
