It is with heavy heart and profound sadness that
we report the passing of Dr. Temba Shonhiwa on 24 October 2009
Temba Shonhiwa (1958-2009): Vita and in Memoriam
by Henry W. Gould
Temba Shonhiwa, the third son of Mawire N. and
Jessica Shonhiwa was born at Chinhoyi, Zimbabwe, 25 May 1958. He
attended high school at Moleli Secondary School in Zimbabwe and Oxford
College for Further Education, United Kingdom in 1980. In 1981, he
entered the University of Zimbabwe, graduating with a B.Sc. with Honors
in Mathematics in 1983. In 1984 he entered Bristol University, in the
United Kingdom, graduating with a M.Sc. in Applied Mathematics. In
January 1986, he joined as a lecturer in the Mathematics Department at
the University of Zimbabwe. He was married to his wife Fortune on 18
June 1990. In January 1991, he joined West Virginia University,
Morgantown, W.Va., USA, as a Graduate Teaching Assistant. He graduated
at WVU with a Ph.D. in Pure Mathematics in May 1996, having written a
dissertation in Number Theory under the supervision of Professor Henry
W. Gould. This work involved two aspects: (i) Solution of a Problem of
Gould posed in 1964; (ii) New results about number theoretic functions
studied by E. Cesaro.
Academic awards included: the Beit Scholarship at
Moleli Secondary School, the British Council Scholarship at Oxford
College for Further Education, the Staff Development and State Lottery
Fellowships at the University of Zimbabwe, and a College of Arts and
Sciences Fellowship at West Virginia University.
His teaching experience included Chair of
Mathematics at the University of Zimbabwe at Harare, Graduate Teaching
Assistant at West Virginia University, Chowan College at Murfreesboro,
N.C., USA, Univesity of Swaziland, and Senior Lecturer at Wits University, Johannesburg, South
Africa.
He also served as President of the Southern Africa Mathematical
Sciences Association (SAMSA) in 2008. SAMSA embraces all colleagues of
the Southern African Development Community (SADC) region and beyond.
Dr. Shonhiwa was a prominent member of the
Mathematicians of the African Diaspora. See the web page maintained by
Dr. Scott W. Williams at the State University of New York at Buffalo.
Temba was very active in South Africa in organizing opposition to the
deterioraring political situation in his home country of Zimbabwe.
Temba was a staunch supporter of freedom and good government.
A few years ago Temba Shonhiwa was diagnosed with
colon cancer and underwent an extensive operation and treatments,
but the cancer returned and he passed away on 24 October 2009 and
was buried on 31 October 2009 in Zimbabwe.
Temba is survived by his wife Fortune, his son
Tatenda, his father, 3 brothers, a sister and several nieces and
nephews.
Temba Shonhiwa and his wife Fortune were active
participants in the wedding when my wife Jean West Gould and I were
married in Mannington, W.Va. on 12 October 1996. They gave us wedding
blessings in their native Shona Language. We became very close friends
and Temba and Fortune told us so much about the history, scenic
attractions and archaeological remains to be found in Zimbabwe, a
beautiful country with a temperate climate. They always wanted us to
visit Zimbabwe. Fortune was also a graduate of West Virginia University.
In October 1998. on the occasion of a Symposium
for my 70th birthday, Temba was scheduled to give a lecture at WVU on
"Generalized bracket function inverse pairs" but he was unable to
attend.
In just the past months before his death, Temba and
I discussed ideas for further joint research papers. He had the
remarkable ability to see a new step without having it spelled out
explicitly, and this was the mark of a highly gifted researcher. He had
so much to live for. Beyond his mathematical talent he was, above all,
a gentleman, a scholar and a "Mensch".
Fortune has written me in a brief email received 9 November:
"Hi Henry and Jean,
Yes you have found me and yes Temba has been taken away from us. My heart is so sore. He passed away on the 24th October and was buried on the 31st October in Zimbabwe. I have just come back this past weekend. It is extremely tough and painful for me right now..... I know your heart is just as sore. He was so special and he still had so much to give to the world."
Indeed Temba will be sorely missed. He was a great
credit to West Virginia University, to Zimbabwe, and to mathematics in
Africa in general and to the whole world.

mailed 29 October 2009:
"Henry - I heard the sad business concerning the death of Temba, one of
your former students. Do know that many are thinking of this loss, but
are also thankful for your influence on this WVU student. Rudy"

Prof. George Andrews, President of the American Mathematical Society, wrote by email on 2 Nov. 2009 as follows:
Dear Henry,
This is terribly sad and comes as a great shock. I well remember the
examination of Shonhiwa. It was a wonderful day and a wonderful moment.
This is a grievous loss. We all will mourn his death.
Sincerely,
George

Professor Arnold Knopfmacher, Department of Mathemnatics,Wits University, wrote by email 28 October 2009:
Dear Henry,
A further message I received:
Dear Professor Knopfmacher,
I was a bit surprised to learn in September that Temba has been
hospitalized because when he left in August to devote all his time to
medical care, he was still strong enough to walk himself to his
second-floor office. However, I got the real shock when I paid him a
first visit at the hospital and realized how quickly his health had
deteriorated. He had also lost much more weight. At the next visit, I
discovered that despite all, not only his mind and senses had remained
perfect, but he was also really happy on that day, he ate the food that
I had brought for him, and even told me that he would like some orange
juice the next time that I come. That day, he also wrote down himself
for me his home and cell numbers, and his brother who was in the room
came next to him to check for the correctness, but just approved. Later
on, I couldn't believe my eyes that the numbers that he wrote were not
only correct, but showed no sign of illness.
The last time I paid him a visit was immediately after the
announcement by the school that his medical expenses have been approved
by the Medical Aid. Thus I brought him some chips and some orange juice
to congratulate him. Unfortunately, although he was still quite strong
(he even quite easily got up from the bed by himself), he wasn't really
happy this time. While I was trying to explain that the treatment should
now be speeded up, he said only his wife knew about the current status of
that process.
When I left that day, I smiled to him, confident that he will
recover.
Through all this experience, I can just say that Temba was a very
bright and strong personality, full with the sense of truth and peace.
May his soul rest in peace, and may the Lord welcome him and bless
his family.

Professor Knopfmacher sent me on 28 Oct. a copy of the Memorial
Programme for the funeral which contains a short obituary. He also sent
a copy of a statement by Augustine O. Munagi, a colleague of Dr. Shonhiwa's at Wits University, who wrote as follows:
On Dr Temba Shonhiwa,
I first met Dr Shonhiwa in
2006 when I joined Wits
University. We soon found
that our areas of research interests have an important component in common
namely, Elementary Number Theory - while I specialize in the elementary theory of
partitions of numbers, Dr Shonhiwa dealt mostly with arithmetic functions. We
proposed some research ideas and spent many leisure hours discussing
mathematics. Dr Shonhiwa was passionate about mathematics research and this
attitude of his influenced me positively. Our only published joint paper is
"On the partitions of a number into arithmetic progressions", which
appeared in Journal of Integer Sequences (Vol. 11 (2008), no. 08.5.4).
We also brainstormed out and
explored the rudiments of what Dr Shonhiwa called "The Theory of
Arithmetic Vector Functions". We opened a text file and accumulated ideas,
with lots of ingenious input from him. Owing to his sudden death, it will take
me much longer to complete the article, working solo. Nonetheless, this is one
project that must be finished and publicized in Dr Shonhiwa's honor, albeit
posthumously.
Lately, we discussed the
notion of relatively-prime subsets, and considered an extension of the
well-studied flat case to PAIRWISE-relatively-prime subsets. This problem
turned out to be very hard even though we obtained a few special results.
However, drawing from his
rich background on the "relatively-prime" theme, he independently
completed an article on relatively-prime subsets which he submitted to the
INTEGERS journal at about June 2009. The manuscript is probably still
undergoing the usual refereeing process prior to acceptance for publication.
The death of Dr Shonhiwa hit
me as a great loss. I will miss him as a friend and as a genial mathematics
collaborator.

Eddie Cross has passed on this modified version of the poem, authored by a Zimbabwean Professor of Mathematics at University of the Witwatersrand (South Africa), Dr. Temba Shonhiwa, entitled "First they Came for the Farmers":
First They Came for the Farmers
First they came for the Farmers
and I did not speak out
because I was not a farmer.
Then they came for the MDC activists
and I did not speak out
because I was not an MDC activist.
Then they came for the trade unionists

Then they came for the industrialists/merchants and I did not speak out because I was not an industrialist/merchant.
Then they came for the landlords

Comment: Temba's love of freedom and resistance to oppression is shown so vividly in his varation on Martin
Niemöller's famous poem.
