Prompt
Create a realistic portrait of Hermann Muller, a middle-aged man with a serious expression, wearing a suit and tie, standing in front of a backdrop that subtly suggests his work in genetics and radiobiology, such as a faint image of a DNA double helix or a laboratory setting. Incorporate elements that reflect his achievements, like a Nobel Prize medal or a subtle X-ray imagery pattern in the background. Capture his determined and intellectual demeanor, characteristic of a renowned biologist and professor.
