Prompt
Generate a realistic portrait of Sir William Boog Leishman, a middle-aged man from the late 19th and early 20th centuries, dressed in a formal British Army medical officer uniform, with a dignified expression, set against a backdrop that subtly suggests his contributions to medicine, such as a laboratory or a tropical medicine setting, incorporating symbols or elements that reflect his achievements in pathology, bacteriology, and parasitology, such as a microscope, a specimen jar, or a hint of a map indicating regions affected by Leishmaniasis.
