As the McMath Planetarium went up at the Cranbrook Institute of Science over the course of the summer of 1955, students took the opportunity to work on their outdoor sketching. Here a young woman captures the newly constructed dome still clad in scaffolding. Note the sign to the left of the planetarium: it reads “Michigan’s First Public Planetarium.”
* “En plein air” is an expression that refers to the practice of painting outdoors – or “in the open air” – which was popularized by Impressionist painters, many of whom made the use of natural light a hallmark of their work. We apologize for the corny “en plein air”/”planetarium” joke, but we just couldn’t resist.
