Reference excerpt

Pierre de Villiers Pienaar (1904–1978) was a South African Afrikaans academic and Professor at University of the Witwatersrand (Wits) and later at University of Pretoria, who pioneered speech language therapy in South Africa and specialising in audiology and lexicography as well as being an Afrikaans author. As lexicographer in 1973, he was part of the group of authors that established the Afrikaans Explanatory Dictionary (Afrikaans Verklarende Woordeboek) alongside Prof M.S.B. Kritzinger and Prof F.J. Labuschagne.

Biography

Early life and education Pierre de Villiers Pienaar was born on 11 August 1904 on the farm Elandsfontein, Gatsrand (currently in the Fochville district), that was destroyed in The Anglo-Boer War during the scorched earth policy campaign. He attended the primary farm school on Elandsfontein, and then went to Boy's High, Potchefstroom, where he matriculated in the first class in 1921. In 1922 he entered the university of the Witwatersrand and the Johannesburg Teachers Training College. He received the B.A. degree in education the beginning of 1925, and later that year the Honours B.A. degree in the first class. In 1926 the University of the Witwatersrand awarded him the degree Master of Arts with distinction for his research in phonetics and general linguistics. The following year Pienaar was awarded a union bursary to further his studies in Utrecht, Netherlands (September 1927 – April 1928), and Hamburg, Germany (1928–1929), where he continued his research in general linguistics and the phonetics of Afrikaans at the Department of Experimental Phonetics of the University of Hamburg. Here, under the leadership of Prof. G. Panconcelli-Calzia, he was awarded the PhD degree in 1929. The Elandsfontein farm was where renowned Boer War scout, Danie Theron, was temporarily buried after his death in combat in the Fochville area during September 1900. (Theron was reburied in 1903 to the family cemetery of his late fiancée Hannie Neethling, on her father's farm Eikenhof.)

Academic career Pienaar taught at several schools on the Witwatersrand and Nylstroom (1926–1927 and on his return to South Africa, 1930–1932). In 1933 he was appointed lecturer in the Department of African Languages, University of the Witwatersrand, Johannesburg, under the headship of Prof. C.M. Doke. He was promoted to senior lecturer in Phonetics and Logopedics in 1938, and through his efforts the first diploma course in Logopedics in South Africa was instituted soon after he had established the Speech, Voice and Hearing Clinic at this university. He developed this section of the Department of African Languages to such an extent that, in 1944, it became the separate Department of Phonetics, Linguistics and Logopedics with Pienaar as head and also director of the associated Speech, Voice and Hearing Clinic. Through his efforts the University of the Witwatersrand in 1948, instituted a four-year degree course with Phonetics and Logopedics as major subjects, the first of its kind in South Africa. He remained head of this department till the end of 1956. In 1957 he joined the University of South Africa for two years as Professor of Afrikaans and Netherlands Linguistics. During this time he put forward proposals to create a professional degree course in Logopedics at the university of Pretoria. In 1959 Pienaar was appointed professor and head of the new Department of Speech Science, Logopedics and Audiology at the University of Pretoria. This department also incorporated a speech, voice and hearing clinic, of which he was the Director. He chaired this department and remained Director of the clinic till the end of 1969 when he reached retirement age. To benefit from his vast experience, the University of Pretoria continued to retain his services by appointing him as temporary lecturer in 1970. He held this appointment as Professor Emeritus in the department for two years, and became honorary professor for the period 1973–1974. In 1973 he opened a private consulting room in Pretoria for the rehabilitation of persons with voice disorders. In his retirement he was still engaged in the field of Afrikaans phonetics. He was appointed head of the speech archives sponsored by the Department of National Education and the Human Sciences Research Council. Among his students who majored in phonetics, three have become heads of university departments of Phonetics or African Languages in South Africa (L. W. Langham, D. T. Cole, and E. O. J. Westphall). During his tenure at the universities he persuaded the Departments of Education of all the South African provinces to appoint speech therapists and audiologists in schools, hospitals and other institutions, thus improving the speech and hearing of thousands of people. His diagnostic acumen and therapeutic skill with voice disordered cases have earned the respect of several ear, nose and throat specialists who increasingly referred cases of this nature to him and the speech therapists that he had trained. Pienaar was a member of several scientific societies and served on a number of commissions, committees and councils of the Government and other institutions such as the South African Broadcasting Corporation (SABC), the Department of Education, the Film Council, the Department of Health, the South African Academy of Arts and Science, the Transoranje Institute for Special Education, the South African Council for the Deaf, and others. Noteworthy, he served on the Language Advisory Committee of the SABC (1957–1968); the Advisory Committee for Language Laboratories of the Government Department of Education, Arts and Science; the Film Board of the Republic of South Africa since its inception; the Board of the Transoranje Institute for Special Education as representative of the Department of National Education; the editorial board of Folia Phoniatrica, the journal published by the International Logopedic and Phoniatric Society; the Commission appointed by the Department of Health to investigate the use and abuse of hearing aids in South Africa; clinical and technical committees of the South African Council for the Deaf, the Transoranje School for Partially Hearing Children, the National Committee for Noise Control in South Africa, and the South African Speech and Hearing Association. He advised several national and international universities on the training of therapists in the field of communication pathology. Others asked his advice on setting up language laboratories.

Worked examples

Example 1 — a first encounter with Pierre de Villiers Pienaar

Start with the simplest possible case. Write down what Pierre de Villiers Pienaar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pierre de Villiers Pienaar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pierre de Villiers Pienaar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pierre de Villiers Pienaar

In research
Pierre de Villiers Pienaar appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pierre de Villiers Pienaar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pierre de Villiers Pienaar is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1904 births, 1978 deaths, 20th-century lexicographers, so understanding it makes those chapters shorter.
In everyday life
Look for Pierre de Villiers Pienaar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
