If you read the article again, you will see that it refers to the earlier case of the suit being cut by his sword. He then tried again, and was dashed on the rocks. The San Francisco press must have been perceptive, because when he moved to Australia soon after this, the Australian press fawned over him.
He presented himself as Professor Clampett in Australia, and was involved with the YMCA. He was interested in the benefits of exercise, something he no doubt learned from his younger brother the Rev Frederick W Clampett, who had a life-long interest in the YMCA.
Arthur must have stayed with the Rev in New York when he first arrived in the US from Ireland in about 1883, when the Rev was an assistant reverend at St Bartholomew's church. The Rev was the Rector at Trinity Episcopalian Church, San Francisco, 1900-1920, and it is difficult to imagine a greater contrast between two brothers.
Arthur was also a very good singer.
Then if you look at the NZ newspapers, he spent a while passing himself off as an evangelist called Sullivan, but was eventually exposed in 1889 by people who knew him by his real name.
There was an article in the Waterford press, Ireland, in 1864, which read "A fine little boy 6 years, 2nd son of Robert Clampett of Manor street was knocked on the road, and the cart rolled over his head. One, if not both, of his jaw bones was broken, besides other injuries, particularly about the head." By his age, this boy was Arthur, and this head injury might explain his compulsion to lie. He could have made a good living from singing and lecturing, but could not stop lying about himself.
I saw that later article, and was interested to see that Boynton did not think much of Arthur. Never mind, the ladies loved Arthur!
