In June 1914, when Henderson was 19, his father took the family on a vacation-business trip to Europe. They saw fields of flowers and bought necessary oils from the French. The family also visited the oil factories that made the perfume for the California Perfume Company.[3]
From 1912 to 1915, Henderson attended the New York Military Academy, a boarding school at Cornwall-on-Hudson, New York, south of Newburgh.[4] By midyear in 1916, he decided to leave Dartmouth and volunteer for the U.
