Dr. Gardner traveled several times to Europe, in 1908, 1910, and 1911, likely in connection with his work as a chemist/pharmacist. He also traveled in the U.S., as mentioned in a brief article in August, 1909:8, 9, 10
Dr. Edward W. Gardner, of Orange, who is making an automobile tour through the White Mountains, was at Manchester, Vt., yesterday.11
After Edward’s death, his wife Marie also traveled several times to Europe. On her passport application in 1922, she names her husband as Edward W. Gardner, “died February 1910 in Orange, NJ.” This is contradicted by Edward’s listing in the passenger list in August 1911. It seems likely that Marie was confusing Edward’s death with that of his father, which was in February 1911 in Orange, NJ. In fact, Edward’s obituary, listed in several newspapers, shows that he died on 11 February 1913 in Twilight Park, New York. One version appears below:7, 12
Edward Winslow Gardner, son of the late Robert W. Gardner of Bloomfield, died last Thursday [11 December 1913] at Twilight, N.Y. He was a chemist and took charge of the chemical plant of his father in Orange on the latter’s death three years ago. He is survived by his wife, his mother, Mrs. R. W. Gardner, and a brother, Robert H. Gardner, both the latter of Bloomfield. Funeral services will be held tomorrow afternoon at the home of his mother, 50 Broad Street, Bloomfield.
The various obituaries for Edward consistently omit a mention of his son Edward Theodore Gardner, who was about six years old when Edward died. Also, his wife Marie is never named, and his funeral was from his mother’s home, not his wife’s. It seems possible that Edward was separated or estranged from his wife, which would explain the artifacts in his obituary, his frequent travels alone, absence of his listing in the 1910 census with his family, and his death in New York, far from home.
