Life

Dietrich Heinrich Hennig was born in the 18th century at the time of the Electorate of Hanover during the personal union between Great Britain and Hanover . In the so-called " French era " he was a soldier in the Battle of Leipzig against the troops of the French Emperor Napoleon Bonaparte . He later wrote about this in his personal memoirs published by Th. Schäfer in Linden near Hanover .

The memorial at the Ahlem shaft commemorates the slave laborers who worked there in the Hanover-Ahlem sub-concentration camp at the time of National Socialism

At the beginning of industrialization in the Kingdom of Hanover, Henning was initially only active as an innkeeper in the early 1840s at the latest , when in 1842 he just by chance rediscovered an asphalt deposit in the immediate vicinity of the sulfur springs of the Limmerbrunnen , which was known and described as early as 1730, but has not yet been used had been. These deposits of bituminous rock were found on what would later become Harenberger Straße, later renamed Heisterbergallee.

In 1843, Henning founded a factory for processing asphalt mastic in Limmer an der later Schwanenburg on the site of the later University of Hanover , which was also the first German factory for processing asphalt. The rock could initially still be extracted in open-cast mining and was only broken up in the course of industrial use in mining .

As an exhibitor at the First World Exhibition in London in 1851, Dietrich Heinrich Henning's company was awarded a medal for the "Mastic breads for mastic asphalt " it produced , ahead of the partly older competitors from other countries. Other German companies in these industries did not yet exist at that time.

In the address book of the royal capital and residence city of Hanover from 1854, the company DH Hennig advertised in large format with, among other things, the image of the medal received.

Hennig was awarded the title of royal court asphalt manufacturer by the sovereign from the House of Welfs .

It was not until 1860 that the entrepreneur August Egestorff acquired a neighboring asphalt warehouse and also founded a factory, albeit in Linden . Soon after, Henning and Egestorff merged to form the new company DH Henning and August Egestorff in order to be able to use the synergy advantages economically.

Also at the beginning of the 1860s, the now enlarged company also acquired a company in the Hils -Höhenzug near Vorwohle. The rock of the asphalt mine operated there had a significantly harder structure and a lower bitumen content than the rock extracted from Limmer. At first the occurrences near Limmer and those in Hils were the only known ones in Germany.

In the year of the proclamation of the German Empire in 1871, the companies and their deposits became the property of the English United Limmer and Vorwohle Rock Asphalte Company . This also The British Limmer and Vorwohle rock Company Ltd. named company was also referred to as "English Asphalt" in Germany.

A generation later found themselves on both sides of Harenberger street in Ahlem and later up to Velber underground tunnels in which the period of National Socialism people as forced laborers toil had. Other parts of the tunnels served the population as protection from the aerial bombs during the air raids on Hanover .

The municipal authorities of Hanover temporarily leased the open pits near Velber in order to fill them up with waste from the garbage disposal. The huge asphalt pit on Harenberger Strasse in Ahlem was filled with rubble and topsoil after the end of the Second World War . Residential buildings were then erected above this.
