Today In History with The Retrospectors

Leonarde Keeler, inventor of the modern polygraph, first showcased his device in a courtroom on 2nd February, 1935. The wooden box, which measured physiological responses like blood pressure and respiration, took the stand alongside him, and, while Keeler emphasized the machine wasn’t infallible, he later told journalists assembled outside the venue that his invention would soon revolutionise criminal justice.

Keeler’s innovations built upon earlier work by others, including Scottish cardiologist James McKenzie, who created a device to detect heart arrhythmias, and Dr. William Moulton Marston, who later linked blood pressure changes to emotional responses - and, inspired by his "truth-telling" research, would go on to create Wonder Woman. But Keeler’s talent for self-promotion, using dramatic applications of his polygraph, made his name, and cemented the device’s reputation as a “lie detector” (a term he never actually used).

In this episode, Arion, Rebecca and Olly discover how the polygraph - now discredited as evidence in US courts - once put a Death Row inmate to the electric chair; reveal how Keeler’s mentors gradually drifted away from the ‘monster’ they had created; and explain how the men who invented the ‘truth machines’ of the 20th century had an uncanny talent for meeting their wives at work…

Revolutionary leader Oliver Cromwell was executed on 30th January, 1661 - despite having been dead for more than two years. His body was exhumed from its tomb in Westminster Abbey on the instruction of King Charles II, who sought retribution for those involved in the trial and execution of his father, Charles I.

Along with other Regicides, Cromwell’s corpse was disinterred and subjected to public abuse. On the anniversary of Charles I’s beheading, Cromwell’s head was mounted on a spike and stuck on the roof of Westminster Hall - where it remained for thirty years.

In this episode, Arion, Rebecca and Olly track the illustrious history of Cromwell’s head from that date forth; consider whether the crowd in attendance at the ‘execution’ really hated their former Lord Protector as much as their jeering suggests; and explain how the intervention of a future Prime Minister prevented Cromwell’s relic being put on public display as recently as the 19th Century…

The BBC broadcast the first ever edition of Roy Plomley’s ‘Desert Island Discs’ - the world’s longest-running interview programme - on 29th January, 1942. 

Opening, as the show still does, with Eric Coates’s theme music ‘By the Sleepy Lagoon’, the episode welcomed comedian Vic Oliver as the series’ first ‘castaway’. Plomely would go on to present a further 1,785 editions of the show until his death in 1985.

In this episode, Arion, Rebecca and Olly consider the metaphor of an abundant and sunlit desert island in the context of the horrors of the Blitz; discover how BBC censors ensured early episodes lacked the free-wheeling quality modern listeners expect; and reveal the most-chosen artists across the show’s incredible archive…

Stud-and-tube bricks, which paved the way for Lego to become one of the most successful companies in Denmark, were patented on 28th January, 1958. But this family business had already been in existence for 26 years, mostly making wooden toys.

It later emerged, however, that the plastic self-locking bricks that brought them so much success had in fact already been invented - and patented - by British toymaker Hillary Page in 1940.

In this episode, Arion, Rebecca and Olly explain how Lego’s lawyers stay one step ahead of their imitators; unconvincingly demonstrate how to pronounce ‘Skoda’; and reveal how branded toys - a controversial pivot for the company in the ‘90s - helped save the business…

The corpse of Vladimir Lenin, founder of the Soviet Union, was placed on display in Moscow's Red Square on 27th January, 1924 - where, astonishingly, he remains viewable to this day. 

He’d wanted to be buried next to his mother in Saint Petersburg, but after he suffered a series of strokes, the Soviet government instead secretly planned to build a mausoleum for his body, in part to deify him as a quasi-religious figure.

In this episode, Arion, Rebecca and Olly explain how pioneering embalming techniques were created by ‘The Lenin Lab’ to look after the cadaver; ponder how mausoleum architect Alexey Shchusev contented with the January freeze; and consider whether an embalmed Queen Victoria would be just as popular a tourist attraction…
