Dermot Manning and colleagues at ICI – Plastic Fantastic

The commercial success of PE starts with Reginald Gibson, Eric Fawcett, Michael Perrin and Dermot Manning at ICI. Claudia Flavell-While tells their story

POLYETHYLENE (PE) – or polythene as it’s still known to many – is, quite literally, everywhere. Low-density polyethylene (LDPE) shopping bags are used to carry home clingfilm (also LDPE), freezer bags (very low-density polyethylene, or VLDPE), bubble wrap and Tupperware food containers (linear low density polyethylene, or LLDPE), milk bottles, detergent bottles, margarine tubs and plastic toys (all made from high density polyethylene, or HDPE).

Meanwhile your water and gas may well reach you via a pipe made of medium density polyethylene (MDPE); the water pipes inside your home, if they aren’t copper, are almost certainly cross-linked polyethylene (PEX); and if you’re unlucky enough to have needed a hip or knee replacement operation, the articulated section of the joint is probably made from ultra-high molecular weight polyethylene (UHMWPE).

In short, PE is an incredibly versatile material, which has made it the world’s most important and most produced plastic, with production running to around 80m t/y.

As one might expect, chemical engineers had a crucial hand in its discovery and commercialisation.

PE was discovered twice, each time by accident. The German chemist Hans von Pechmann was the first to synthesise it, in 1898, as an unexpected result of heating diazomethane. In 1933 itwas discovered again by two research chemists, Reginald Gibson and Eric Fawcett, working at ICI Alkali’s research laboratories in Winnington, UK. A third chemist, Michael Perrin, made the crucial breakthrough in understanding PE and its production that turned a fluke discovery into a reproducible reaction. But it was a chemical engineer, Dermot Manning, who built the high-pressure research reactor that made the experiment possible, as well as the larger reactors subseq

PDF Transcript of "'We Have Them Whipped Here': Lynching and the Rule of Law in Lima, Ohio"

Perry Bush:

Thank you all for coming. It's delightful to be here, and it's real honor to win this award, so I'm very grateful. Thank you also for your willingness to flex. I was going to give this in October, and I came down with COVID, and I tell you what. I mean, we have been vaccinated and boosted, and then we got it. So there are just nasty new bugs going around, and you all be careful. I mean, there are worse flus, but it just wipes you out. So I'm grateful that I could come and do this.

Lima was shaken in the late 19th, early 20th century, by two different incidents of racial violence. On one hand it didn't render the city especially unique, lynchings were not uncommon in these years, and neither were they uncommon in the American Midwest. One scholar counted 28 lynchings in Ohio between 1856 and 1932, 45 in Illinois in the same years, and 66 in Indiana in the same period.

And these clearly, these incidents of racial violence were clearly surface manifestations of Gilded Era racism, like the cultural tectonic plates beneath beneath the nation's political, cultural surface. The same forces produced the legal structures of Jim Crow segregation, which of course was de jure in the South, but de facto in practice here, across much of the North. And that relegated people of color to a secondary, and clearly a subordinate place in American life. And you can read the first, this article actually looked at two different of these racial explosions, the Election Day riot of 1888, and then this other, attempted lynchings in 1916. And you could read both those as evidence of this new Gilded Age racism.

I'm going to focus on the second, just for reasons of time, and I'm going to watch my time, and try to get this all in, in the next 35, 40 minutes. Right?

Perry Bush:

Because the attempted lynchings in Lima, in late August of 1916, sent the city's
