The late German language scholar, Prof Klaus von Delft.

On Saturday, 28 August 2021, the University of the Free State (UFS) community lost one of its erstwhile stalwarts: Prof Klaus von Delft, former head of the then Department of German, later section head in the amalgamated Department of Afrikaans and Dutch, German and French

In retrospect, the designation of being a ‘stalwart’ should be qualified, as Von Delft never was swayed by popular institutional opinions of the times, but rather followed an unwavering sense of integrity in everything he did. His impact on German teaching in South Africa, but specifically in the Free State region, can hardly be overestimated: an academic career that started in 1963 and stretched over decades, and that included numerous academic and cultural initiatives to open up the world of Germany and the German-speaking countries to generations of students. Whether it was through the classical works of Goethe and Schiller, the pathos of the Romantics, the irony of the modernists, or writers struggling with existential questions after the Second World War – for many students, Von Delft opened a new world of ideas and sentiments to be explored. And often the exploration ended where it started: learning more about oneself and one’s place in the world through the gift of language and poetry.

Encyclopaedic knowledge of German literature and culture

Born in the small town of Stutterheim in 1937 (his father was a pastor in the Lutheran church), Von Delft spent the years 1939-1949 in Germany, as what should have been only a visit to a sick grandfather was vastly prolonged with the outbreak of the Second World War. The return to South Africa eventually anticipated a university career in Germanistik (German Studies), where he was responsible for teaching both language and literature, although most of his students will probably best remember his encyclopaedic knowledge of German literature and culture. His career saw many changes on different levels – establishing and continuing a high standard of German teaching at tertiary level, navigating changes in the methodology of foreign language teaching, participating in the merger of three language departments, and always doing everything in his power to arouse and cultivate the interest of young people for the world(s) offered by the words and cadences of his mother tongue. But he also was scholar, administrator, and mentor – even during difficult times when the future of German at the UFS seemed bleak to some. His too early retirement as senior professor did not diminish his interest in his discipline, as he remained willing to avail himself for contract lectures for many ensuing years. And it was a great honour to welcome him to the 28th conference of the Association for German Studies in Southern Africa hosted at the UFS in 2019 – the kind words of many members bore testimony to the estimation in which he was held by many colleagues and former colleagues from the community of German scholars.

Remembering Prof Klaus von Delft

Prof Heidi Hudson, Dean of the Faculty of the Humanities; Prof HP van Coller, former head of the Department of Afrikaans and Dutch, German and French; Prof Angelique van Niekerk, Associate Professor: Department of Afrikaans and Dutch, German and French; and Ms Ingrid Smuts, one of his former colleagues and later section head of German, remember Prof Klaus von Delft in the following tributes.  

Prof Heidi Hudson, current Dean of the Faculty of the Humanities, shares the following memories:

I have fond memories of my time as a student in Prof Von Delft’s class, as well as the four years I spent as student assistant in the Department of German. It was only after I left the department that I realised what a great role model he was to me. Klaus von Delft was the epitome of integrity, unwavering, consistent, ‘doing’ principle rather than popularity.  Those formative years in the Department of German fundamentally shaped my outlook on the world. What a privilege it is to have known him.  


Prof HP van Coller, former head of the Department of Afrikaans and Dutch, German and French, remembers him as follows:

 I got to know Klaus von Delft really well on the Research Committee of the Faculty of Arts (together with the Faculty of Social Sciences the precursor of the current Faculty of the Humanities).

For years, he was the chairperson of this important committee, which at the time – before the system was based on research incentives – was in charge of the allocation of research funds, had to approve research projects, and had to either accept or reject reports.

Klaus was an even, balanced, and fair judge of projects, but had little patience for vague and imprecise formulations and anything that, for him, smelled of opportunism. I still remember our long brawl over an application from a visual artist for a research grant to visit overseas museums. To me it was a fair request, to Klaus it sounded like academic tourism. In the end, he relinquished without a word of reproach to me.

I very seldom saw him angry. Except in the case of a colleague who received a large research award, but just could not come up with his report the day before. His first excuse was that a water leak in the library had rendered his report unusable. It was reluctantly accepted by us. But when he offered the same excuse six months later (admittedly, pipes at the time were pitifully bad), it added fuel to the fire and the German's patience ran out.

As a good researcher, Klaus sometimes had his own research play second fiddle, because he tried to advance his discipline in so many fields: as an excellent lecturer who was always available to students, a tireless champion for German in the context of secondary education, choral music in German, etc. But it was with regard to the management of the faculty where he really left deep footprints: always well prepared, always logical, and always polite. After losing the vote for the deanship by a single vote to Andries Snyman, he did not pull back in indignation, or oppose Andries. He actually proved to be Andries' important right-hand man and confidant for many years. Only someone who puts himself second, acts like this.

All in the interest of academia. In the good old times, a gathering place of free spirits that both sought and shared scientific knowledge. This was the kind of academic and human being Klaus von Delft was. The name ‘Renaissance man’, which is used lavishly these days, suits him well. Cultivated lover and connoisseur of music, literature, the classics, art, nature …

Ave atque vale!

Ms Ingrid Smuts, one of his former colleagues and later section head of German at the UFS, remembers him fondly:

I will remember Prof Von Delft as a man of exceptional qualities: humble, thoughtful, kind, generous, never judgmental, compassionate, always dependable, brilliant, and also witty and entertaining. His wisdom, broad knowledge, and work ethic are legendary. He led by example and stimulated his students to give their best. I, like many others, will remember Prof Von Delft arriving at the university on his Vespa scooter to lecture, long after his retirement. His contribution and selfless support will always be appreciated. His qualities have also found expression in his family. The Von Delfts have been an asset to humanity.

Prof Angelique van Niekerk, Associate Professor: Department of Afrikaans and Dutch, German and French

In 2006, I had to go to his house to pick up a rented cello from the Von Delft ‘collection’ for a nine-year-old imp in my own home. When the passion overcame my son’s possible talent at the age of nine and he asked the ‘uncle’ to “Please play something for me so that I can hear which one is the best”, I thought I would die of shame because of my child’s arrogance. Prof Von Delft smiled, sat down with a twinkle in his eye, and enthusiastically played both cellos, which made the young man feel very important, being able to decide which of the two cellos he liked best for his then prospective music lessons. An adult can indeed talk to children as well! 
 
The department gladly welcomed the Von Delfts in our midst, even years after his retirement. Sitting close to me at the table during the year-end function in November 2018, he and his wife, Elna, were still socialising and having a great time with colleagues. He handled the really disturbing and unforeseen music (aimed at a noisy teenage market) of a next-door function with charming dignity. This was true to his nature, and definitely intended to spare the hosts (department and former colleagues) further inconvenience.  

Contribution to the Department of Afrikaans and Dutch, German and French

We honour his memory as human being and his contribution to the department and the Faculty of the Humanities.

Prof Von Delft will be remembered by everyone whose lives he touched – certainly by a large Bloemfontein community of former students, colleagues, family, and friends. And this remembrance is important – as the poet Rainer Maria Rilke wrote: “Wenn ihr mich sucht, sucht in euren Herzen. Habe ich dort eine Bleibe gefunden, lebe ich in euch weiter (When you look for me, look in your own hearts. If I have found a dwelling there, I will live on in you)."

A summary of an inaugural lecture delivered by Prof Robert Bragg at the University of the Free State:

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
