Ariel "Bob" Wills
From The Chocolate Press - June 5, 1926:

“From 1873-1926 and going strong! How many of us will be able to be right on the job, as Bob Wills puts it, in 1979?

“Very few of us, my friends, I’ll wager, but Ariel E. Wills, who has a service record of 53 years is still going strong. He was born in 1846 at East Randolph, Vermont, and was the youngest of ten children. During his fifteen years of boyhood in East Randolph, nobody ever called him Ariel, no, everybody called him Bob, and so it was Bob, who came to Boston, who drove horse-cars in South Boston, it was Bob, who was hired by Mr. Josiah Webb to drive that single team to and from Boston, it was Bob who finally came to work for the Walter Baker Co. and took charge of the stable, and it still is Bob who has become another victim for our mysterious camera man.”
