During his travels, Professor Jones visited several universities through the world where he lectured on his specialty, medieval literature. His wife Anna and only son Henry Jones, Jr. accompanied him. For Henry, the tour was one of the obligations that prevented him from pursuing his life-long quest, to discover the Holy Grail for six years. It wasn't until 1912 until he finally resumed his research."@en . . . . . "The world lecture tour was a turning point in the career of Henry Walton Jones, Senior, beginning in 1908 and lasting till 1910. During his travels, Professor Jones visited several universities through the world where he lectured on his specialty, medieval literature. His wife Anna and only son Henry Jones, Jr. accompanied him. For the young Jones, the journey was of special significance because it was the first time he left his hometown in Princeton for a significant length of time; his first contact with other countries and cultures; his first experience with ancient ruins and artifacts; and his first meeting with several important figures of the time. Strict teacher Helen Seymour was charged with the task to educate Henry Jr. during the long journey. During the tour, the Jones family also visited several friends of Professor Jones, and experienced several detours and delays due to illness of various family members and the occasional misadventure of the younger Jones. For Henry, the tour was one of the obligations that prevented him from pursuing his life-long quest, to discover the Holy Grail for six years. It wasn't until 1912 until he finally resumed his research."@en . .
