Robert Edwin Johnston was not a widely recognized artist during his lifetime, and consequently, there is limited information available about his life and career. He was born in 1883, and he passed away in 1933.
Details about Johnston's artistic education, influences, and the specific genres or mediums he focused on are not well-documented in historical or art records. It is possible that he may have been a local or regional artist, or someone who practiced art as a secondary profession or a hobby.
Without more information, it is challenging to provide a comprehensive biography of Robert Edwin Johnston. He may have been active during a period rich with artistic movements such as Impressionism, Post-Impressionism, and the early stages of Modernism, but without concrete details, one can only speculate about his involvement or contribution to these movements.
Given the lack of information, those interested in Robert Edwin Johnston's work or legacy might need to conduct specialized archival research or consult niche publications or local historical societies that might have records of lesser-known artists from the early 20th century.
