Image of Victorian-era coastal survey equipment found in the NOAA Photo Library.
The equipment belonged to the artist’s grandfather, a Swiss immigrant and West Point math professor. He’s the man who made all America’s gallons the same gallon – before that, it was up to states to decide just how much a gallon was.
