October 5, 1974 –

David Kunst completed the first documented journey around the world on foot. That’s a lot of walking shoes that were worn and worn out.

Kunst’s trek began June 20, 1970, and ended October 5, 1974. Dave started his journey in Waseca, Minnesota, with his brother John, a letter of recommendation from US Senator Hubert Humphrey, a scroll to be signed by officials along the way, $1000, and a mule named Willie Makeit carrying camping supplies.

The brothers walked to New York City with Willie Makeit, then flew to Portugal, where they acquired a second mule (Willie stayed home). Dave and John walked across Europe and visited Monaco, where they met Princess Grace, and Italy, where they encountered Thor Heyerdahl.
