Samuel Alfred Warner

He took service with Pedro I of Brazil in Portugal, and on his return to England found some support from William IV for his claims to have secret weapons.

[2] Warner died in obscure circumstances in the early days of December 1853, and was buried in Brompton cemetery, west London, on the 10th.

[1] Small committees were appointed to examine and experiment on these inventions, but Warner refused to show or in any way explain his secrets till he was assured of the payment of £200,000 for each.

[3] At the same period Warner's claims were assessed by Lieutenant-Colonel Chalmer of the Royal Artillery, and Commander James Crawford Caffin.

Keats and Hardy were long since dead, and it was noted it was singular they should die, and no copy be found, it being notorious they were both men of business and not likely to have lost their papers.

The supposed inventions were displayed in the West End Gallery at the great Exhibition of 1851, still claiming the support of Keats and Hardy, but it progressed no further.
