Gail Borden Jr. was undaunted by failure. In the 1840s he built a wagon meant to travel on land and water but did neither successfully. His nutritional biscuits made from dehydrated meat and flour were unpalatable. Yet Borden kept at it. In the 1850s, he developed a way to condense milk—and this time, succeeded on a grand scale.
