The first published image of Caulobacter-like cells. Film micrograph from 1905 depicting Caulobacter-like cells isolated by Mabel Jones from tap water in Chicago after 72 h in culture. Featured are rosettes of cells formed by descendants of single cells. Stalks are visible in the middle of rosettes, and predivisional and swarmer cells are both visible toward the periphery and in isolation. (Reproduced from reference 2).
