John Munnoch was not a widely recognized artist, so there is limited information on his life and works. He was born in 1889, likely in the United Kingdom, and he died at a young age in 1915, which coincided with the time of World War I. Given the era and his early death, it is possible that he may have been involved in the war, which could have influenced his life and art, or even been the cause of his death.
Unfortunately, with so few records available regarding John Munnoch, it is challenging to provide a comprehensive biography or assess his contributions to the art world. He may have been a local or amateur artist, or perhaps someone whose works have not been preserved or recognized in the mainstream art historical narrative. Many artists of the time were overshadowed by their contemporaries who became more famous, or their works might not have survived due to various circumstances such as the war.
Given the lack of information, it is not possible to detail his artistic style, mediums, or subjects. It is also unclear whether he had any exhibitions, was associated with any particular art movements, or had any notable patrons or supporters.
To gain a deeper understanding of John Munnoch's life and works, further research would be necessary, possibly through historical archives, newspapers of the time, or any surviving family records. It would also be beneficial to search for any local historical societies or museums that might have knowledge of lesser-known artists from the period.
