What professions were photographed holding flasks?

The profession-defining pose is an old idea. Back in the 19th and early 20th centuries, chemists – from Louis Pasteur to Marie Curie – were commonly photographed or painted holding aloft a flask and gazing nobly at its contents.

Ali, for example, says that he and his collaborator often do computations on a blackboard and take an image of them with their mobile phones before erasing the writing and moving on to the next step. “Many a time,” Ali says, “the main idea or the main computation for a project that becomes a paper happens while we are doing these intense computations on a blackboard.”
