1882: George Henry Lamson, aconitine poisoner

Posted on by

On this date in 1882, George Henry Lamson was hanged at England’s Wandsworth Prison for poisoning his brother-in-law in pursuit of an inheritance.

Once decorated for his volunteer medical practicioning in the benighted lands of eastern Europe, Dr. Lamson fell prey upon his return to England to morphine addiction which cleaned out his assets.

Desperate to resolve his debts, he administered a lethal aconitine dose to the paraplegic 18-year-old Percy John.

Apparently, the good doctor had learned all about this efficacious chemical at the knee of Queen Victoria’s own physician, Robert Christison.

Unfortunately, Lamson hadn’t been keeping up with his technical journals in the meantime: Christison had taught him that aconitine poisoning was undetectable, but a forensic technique to identify it had subsequently been developed.

(Minor-league milestone: Lamson’s was the first recorded criminal defense that attempted to blame ptomaine poisoning, a now-discredited theory that death can be induced by alkaloid toxins from decomposing food. But the lawyer making that defense would later write that he not only believed his client guilty, he also thought Lamson had iced his wife’s older brother, Herbert.)

The particulars of Lamson’s trial are recounted at length in this free book, from which we excerpt the interesting description of executioner William Marwood’s craft in arranging the scene.

Lamson was a more powerfully built man than he appeared, weighing upwards of 11 stone 12 Ibs., and the executioner, evidently fearing that hie strength would operate somewhat against a sharp and quick fall, fastened back his shoulders in a manner which precluded all possibility of the culprit resisting the action of the drop …

When the convict was pinioned the procession moved on, the clergyman the meanwhile reading the service of the Church appointed for the burial of the dead, the doomed man respondnig almost inaudibly to the words as they were uttered by the chaplain. It was with great difficulty now that he could walk at all; indeed, it is certain that had he not been supported by the two warders who stood on either side of him, he would have fallen to the earth. Suddenly he came in sight of the gallows, a black structure, about 30 yards distant. The grave, newly dug, was close at hand. The new and terrible spectacle here acted once more with painful effect upon the condemned man, for again he almost halted and fell. But the warders, never leaving hold of him, moved on, while Marwood came behind. At last the gallows was reached, and here the clergyman bade farewell to the prisoner, while Marwood began his preparations with the rope and the beam overhead. With a view to meet any accretion of fear which might now befall the culprit, a wise provision had been made. The drop was so arranged as to part in the middle, after the fashion of two folding doors ; but, lest the doomed man might not be able to stand upon the scaffold without assistance, two planks of deal had been placed over the drop, one on either side of the rope, so that up to the latest moment the two warders supporting the convict might stand securely and hold him up, without danger to themselves or inconvenience to the machinery of the gallows. In this way Lamson was now kept erect while Marwood fastened his legs and put the cap over his eyes. He must have fallen had the arrangement been otherwise, for his effort to appear composed had by this time failed. Indeed, from what now occurred it is evident that the convict yet hoped for a few moments more of life, for, as Marwood proceeded to pull the cap down over his face he pitifully begged that one more prayer might be recited by the chaplain. Willing as the executioner possibly might have been to listen to this request, he had, of course, no power to alter the progress of the service, and was obliged to disregard this last demand of the dying man. Signalling to the warders to withdraw their arms, he drew the lever, which released the bolt under the drop, and so launched the prisoner into eternity, [the] clergyman finished the Lord’s Prayer, in the midst of which he found himself when the lever had been pulled, and then, pronouncing the benediction, moved slowly back to the prison.

Though aconitine poisoning dates back to antiquity (the Greeks figured that the original dog from hell, Cerberus, drooled aconitine) and has been used as a literary device by Oscar Wilde, James Joyce, and J.K. Rowling, Dr. Lamson’s was long the last known case of criminal homicide by aconitine — until the 2009 conviction of a west London woman for slipping this illustrious mickey to her paramour in his chicken curry.

On this day..
