Modderfontein is well known for the location there of the dynamite factory, and this is also how it started life in 1896. It used to be a factory village all out in the country. It is slowly being swamped by urban sprawl. And now even more so since a Chinese company has bought the whole area with plans to develop it. GPS coordinates: 26.09924°S 28.151465°E elevation: 1558m.
Franz Hoenig came out to South Africa in 1895 with instructions from the Nobel company in Hamburg to build a dynamite factory. First production was achieved in June 1896 and full production in November the same year.
Many of the buildings erected in those early days still exist, and are well looked after. There is the house of the factory manager, the Franz Hoenig house, the house of the chief engineer, now the museum, the Club or than it was the casino, the hospital and some buildings in the factory. Over time the factory expanded by adding chemical plants to make ammonia, nitric acid, ammonium nitrate, urea, LAN and a few others. The explosives plant was at one time the biggest dynamite factory in the world.
The village has been changing since AECI started selling off pieces of property in the nineties. All the residential houses of the factory are gone and replaced with town house complexes. But progress not only stopped there, now there is the Gautrain cutting a corridor through the property. And the very latest is that the whole property of about 2400ha has been sold to a Chinese company for development.
The museum is mostly about the village, factory and dynamite production at Modderfontein. The house was originally the residence of the Chief Engineer. In addition there is the Franz Hoenig house, the first factory manager, and an outside exhibition of machinery. Here I found this large compressor, an Ingersol Rand machine. Two stages with an intercooler in between, turning at 214 rpm(revs per minute) and drawing 600kW. And why do I pay so much attention to this machine? It's because I used to operate it, about 50 years ago. On the right is an extract from my note book, and we now know that the crankcase lubricator had to run at two drops per minute. Sorry you can't read it, in those days I was in between writing in German and English.
The house build in 1896 for the first factory manager, it is well worth a visit, having been kept in the style of the late 19th century.
This was the recreation club for managers and senior staff built by Franz Hoenig. There was another venue for the workers. Now it is the office of Zendai (see below).
In Front of the club is a memorial to the employees who lost their lifes during the two world wars. I like to go into more detail here since I don't think this memorial gets that much attention. The inscription reads:
|British South African Explosives||African Explosives and Chemical Industries|
|Roll of Honour||Roll of Honour|
|1914-1918||Employees of Modderfontein factory who gave their lives|
|D. Duffy||in the second great war 1939-1945|
|P.H.Harries||JD De Jongh|
|TAC McCarr||JF Mills|
|L van Brugel|
This refers to the sale of the property to a Chinese company, Zendai. That is 2400ha in total. I am not sure it includes the factory.
The plan is, and we had a quick run down, to build a new city with high rise buildings housing about 100 000 people. Total investment over the next 15 years is envisaged to be R84 Billion. I borrowed the picture from their brochure, I hope they forgive me. It certainly is a shot in the arm for the country and I wish them best of luck.
Otherwise known as 'the little church in the woods'. Officially it is the Chapel of St Francis in the Woods. It was erected in 1953, the foundation stone was laid by the then factory manager, Edwin Taberner.
I am not sure when this was built, looking at the architecture possibly in the 30th or 40th of last century.
I am only including it because this is where I stayed for about a year, 1965/66, before being transferred to Sasolburg. It was the men's single quarters for the factory workers.
During that year I worked on the Ammonium Nitrate plant, the old Fauser plant established in the 1930th, and on the Nitric Acid plants, POP 2 and 3, that is where I operated the compressor above. All these plants are gone now.
