Vietoris studied mathematics and geometry at the Vienna University of Technology. He was drafted in 1914 in World War I and was wounded in September that same year. On 4 November 1918, one week before the Armistice of Villa Giusti, he became an Italian prisoner of war. After returning to Austria, he attended the University of Vienna, where he earned his Ph.D. in 1920, with a thesis written under the supervision of Gustav von Escherich and Wilhelm Wirtinger.
Vietoris was survived by his six daughters, 17 grandchildren, and 30 great-grandchildren.
He lends his name to a few mathematical concepts:
- Vietoris topology (see topological space)
- Vietoris homology (see homology theory)
- Mayer–Vietoris sequence
- Vietoris–Begle mapping theorem
- Vietoris–Rips complex
Vietoris remained scientifically active in his later years, even writing one paper on trigonometric sums at the age of 103.
Vietoris lived to be 110 years and 309 days old, and became the oldest verified Austrian man ever.
