1/4: Why is a thin nasal feeding tube often called a ‘Dobhoff’? The original thin-caliber, weighted feeding tube was invented in 1975 by Dr. Robert Dobbie and Dr. James Hoffmeister. They joined their names for ‘Dobhoff’ (and also used the spelling ‘Dobbhoff’ interchangeably). 
2/4: Dobbie was a surgical attending @utmedicalcenter focused on nutrition for lung & esophageal CA pts & Hoffmeister was a surgical resident. Until the Dobhoff tube, typical feeding tubes were 18 French (or larger) red rubber tubes, that usually only reached the stomach.
3/4 The original ‘Dobhoff’ tube was a ~7-8 French tube (0.095” diameter) made of silastic and PVC, and with a mercury-filled tip.
4/4 The inventors tested the tube on friends & colleagues (incl. Dr. Dobbie’s secretary, shown here). Dr. Dobbie demonstrated the comfort of his tube by giving full academic presentations w/a Dobhoff tube in his nose (& occasionally attending cocktail hours w/tube in place).
