Frank Clapcott was born in New Zealand, probably in 1865. As a young man he came to Patagonia, where he worked for many years on the ranches of the Menéndez family. He was noted for his gift with animals, which were docile under his care and direction. His final years were spent at Estancia «María Behety», in Tierra del Fuego. He was buried at Río Grande in 1946.
