The name Musk probably brings business magnate Elon Musk to mind, but few are aware that a second Musk brother exists, who is quite successful in the food world. Kimbal Musk, the Musk family's middle child, has amassed a $500 million fortune, making him the world's richest chef.

Kimbal Musk is the owner of The Kitchen Restaurant Group, which owns and runs the well-known Colorado eatery, The Kitchen. With an eco-friendly approach that involves locally-sourced ingredients and the use of only biodegradable materials, The Kitchen was named Colorado’s top farm-to-table restaurant by Food & Wine.

The Kitchen Restaurant Group also operates a non-profit called Kitchen Community which teaches children in low-income areas how to grow urban farms and has placed ‘Learning Gardens’ in 330 schools across the country. Musk is also involved in Square Roots, a vertical farming company that brings fresh, local produce to New York City.
