George Carver Clerk, FGA (29 July 1931 – 2 May 2019) was a Ghanaian botanist and plant pathologist. A professor and later, an emeritus professor at the University of Ghana, Legon, he also focused his research on West African mycology and ecology. Clerk, along with his academic contemporary Ebenezer Laing (1931–2015), was one of Ghana’s earliest practitioners of botany as a scientific discipline, in addition to his pioneering role as a plant pathologist in West Africa. In 1973, G. C. Clerk became a Fellow of the Ghana Academy of Arts and Sciences.

Early life and family

George Clerk was born on 29 July 1931 in Accra, Gold Coast. His father, Carl Henry Clerk (1895 – 1982), an agricultural educator, journalist and Presbyterian minister was elected the fourth Synod Clerk of the Presbyterian Church of the Gold Coast from 1950 to 1954 and the Editor of the Christian Messenger, the newspaper of the Presbyterian Church of Ghana from 1960 to 1963. His mother, Martha Ayorkor Quao (1911 – 1989) was from La and Ga-Mashie. Quao’s maternal grandfather was Nii Ngleshie Addy I, the first son of Nii Tetteh Tsuru I, the founder and ruler of the Otuopai Clan, a royal house in Ga Mashie. G. C. Clerk’s father who had earlier studied agricultural science at Tuskegee University, incidentally named him after the American botanist, George Washington Carver, whose works the older Clerk had studied at the Institute, perhaps a foreshadowing of the infant George’s future career path.

George C. Clerk belonged to the historically notable Clerk family. His paternal great-grandfather, Alexander Worthy Clerk (1820 – 1906), a Jamaican Moravian educator arrived in the Danish Protectorate of Christiansborg, now Osu, in Accra in 1843, as part of the original group of 24 West Indians employed by the Swiss-based Basel Evangelical Missionary Society. A. W. Clerk co-established a boys’ middle boarding school, the Salem School in 1843. His paternal great-grandmother, Pauline Hesse (1831–1909) was from the Gold Coast, and was of Euro-Ga heritage. His great-grandaunt was Regina Hesse (1832–1898), a pioneer educator. His grandfather, Nicholas Timothy Clerk (1862 – 1961), a theologian, was the first Synod Clerk of the Presbyterian Church of the Gold Coast from 1918 to 1932, and a co-founder of the Presbyterian Boys’ Secondary School, established in 1938. His grandmother, Anna Alice Meyer (1873 – 1934) was also a Euro-African.

His uncle, Theodore S. Clerk (1909 – 1965) was the first Ghanaian architect and planned the port city, Tema. G. C. Clerk’s aunts were Jane E. Clerk (1904 – 1999), a pioneer education administratior and Matilda J. Clerk (1916 – 1984), the second Ghanaian woman in orthodox-medicine. Pauline M. Clerk (1935 – 2013), a diplomat and presidential advisor, was his cousin, as was Alexander Adu Clerk (born 1947), a sleep medicine specialist and psychiatrist. George Clerk’s granduncle was Emmanuel Charles Quist (1880 – 1959), a barrister and judge who became the first African President of the Legislative Council from 1949 to 1951, Speaker of the National Assembly of the Gold Coast from 1951 to 1957, and Speaker of the National Assembly of Ghana from March 1957 to November 1957.

Clerk’s maternal uncle was the jurist and judge, Nii Amaa Ollennu (1906 – 1986), elected the Speaker of the Parliament of Ghana during the Second Republic as well as serving as the Chairman of the Presidential Commission and acting President of Ghana from 7 August 1970 to 31 August 1970. His uncle was Nathan Quao (1915 – 2005), a diplomat, educationist and public servant who doubled as a presidential advisor to several Heads of State of Ghana. Moreover, his first cousin was the economist and diplomat, Amon Nikoi (1930 – 2002), appointed the Governor of the Bank of Ghana from 1973 to 1977 and Finance minister from 1979 to 1981.

Education and training

George Clerk was a pupil at Presbyterian primary schools at Somanya and Osu. He attended the boys’ middle boarding school, the Salem School. Clerk had his secondary education at the Presbyterian Boys’ Secondary School, then located in Odumase-Krobo. He enrolled at the University College of the Gold Coast and received his bachelor’s degree in botany with first-class honours and winning the first prize as the best graduating student in botany from the University of London, then the parent institution of the university college. G. C. Clerk was then awarded a postgraduate research fellowship at the University of London and the University of Bristol, and in 1963, earned a joint PhD-DIC in botany, with a sub-concentration in physiological mycology, from Imperial College London where he wrote his dissertation on asexual spores of parasitic fungi growing on the bodies of insects. His doctoral advisor was the British mycologist, Michael Francis Madelin (1931–2007), one of the world’s earliest investigators of conidial fungi and slime moulds.

Career

Prior to his postgraduate studies, Clerk taught biology at Prempeh College for about three years in the late 1950s and also served as a housemaster there. During this period, he was also an instructor in mathematical sciences to adult education students. He then became a researcher at the Plant Services Division of the Ministry of Agriculture. Clerk later became a professor of botany at the University of Ghana, Legon when he joined the institution in 1964. While at the University of Ghana, he served as the Senior Tutor of the Senior Common Room and the Hall Master for Akuafo Hall from 1979 to 1980, a hall he had lived in as a student. He served as the departmental head and was appointed the Dean of Graduate Studies at the university.

He authored more than 250 peer-reviewed scientific publications including journal articles, abstracts, book chapters and textbooks. Clerk’s work on plant diseases in Ghana and West Africa influenced public policies pertaining to plant development, as illustrated by his experimental investigation of the pathogenesis of the black pod disease in the cocoa bean. In 1973, he became a Fellow of the Ghana Academy of Arts and Sciences, the only scholar to be elected that year. George Clerk’s seminal book, Crops and their diseases in Ghana, was published in 1974, and secured the Ghana Book Award in 1982. G. C. Clerk was a Fulbright Scholar at the University of California, Riverside between 1972 and 1973. He was a visiting professor at the Ahmadu Bello and Lagos universities in Nigeria. He assumed the Dean of Science position at the University of Port Harcourt in the mid-eighties.

He was a board director at the Ghana Atomic Energy Commission from 1996 to 1998 along with his academic colleague, Marian Ewurama Addy, the first Ghanaian woman professor of natural science. He was a resource person, chief examiner for biology and a consultant to the West African Examinations Council. He was an external examiner and an assessor for faculty promotions at other institutions of higher education. Clerk was a regional representative of the Association of African Universities. In addition, he was a trustee at major organisations such as the Cocoa Research Institute of Ghana, Council for Scientific and Industrial Research, the Ghana National UNESCO Commission, the Volta Basin Research Project and the Water Research Institute, formerly the Institute for Aquatic Biology.

Personal life

G. C. Clerk was married; his children were Judith, George, Jnr., Nicholas, Theodore, Daniel and Dinah. Clerk was a trained pianist. The second of six siblings, his older brother was Nicholas T. Clerk (1930–2012), a former GIMPA Rector.

Death and funeral

George Clerk died in Accra on 2 May 2019 after a short illness. Clerk’s memorial service was held at the Akuafo Hall Chapel on the campus of the University of Ghana, Legon, before his burial at the Osu Cemetery in Accra.

John Cleese’s net worth, biography, fact, career, awards and life story

John Cleese Net Worth: John Cleese is an English actor, comedian, writer, and producer who has a net worth of $20 million dollars. John Cleese is perhaps most famously known for his work with Monty Python — a British surrealistic comedy troupe responsible for creating the sketch comedy TV show “Monty Python’s Flying Circus,” as well as such films as “Monty Python and the Holy Grail,” “Monty Python’s Life of Brian,” and “Monty Python’s The Meaning of Life.” Early Life: John Marwood Cleese was born on October 27th, 1939 in Weston-super-Mare, Somerset, England — the sole child of Reginald Francis Cleese, who was an insurance salesman, and wife Muriel Evelyn. Cleese’s family surname was originally Cheese, but his father found it to be embarrassing and opted to use Cleese when enlisting in the Army during World War One. Cleese began his early education at St Peter’s Preparatory School where he received awards for his firm command of the English language and literature. Cleese also excelled at such extracurricular activities as cricket and boxing. At age 13, Cleese was awarded an exhibition at Clifton College, a prestigious English public school located in Bristol. John Cleese was incredibly erudite, which gave him the ability to teach several subjects before enrolling at Downing College, Cambridge. He started acting with the Cambridge Footlights and graduated in 1963. Pre-Python Days: John Cleese began writing scripts early and found a place as a cast member for the 1963 Footlights Revue — which was wildly successful at Edinburgh Festival Fringe. With the Footlights Revue, Cleese would come into contact and work with future writing partner Graham Chapman. The Cambridge Footlights became known as the Cambridge Circus, thereafter, traveling internationally. Cleese’s traveling revue brought him to New York, where he appeared in multiple Broadway and Off-Broadway productions and was, as a result of his efforts, offered a job as a writer for BBC Radio. This time of his life would put Cleese in touch with future Python Terry Gilliam, as well as American actress Connie Booth. Cleese worked for “The Dick Emery Show” as well as “I’m Sorry, I’ll Read That Again”. It was his work on “The Frost Report”, that gave Cleese his first appearance on British comedic television and also put him in touch with future Pythons Eric Idle, Michael Palin, and Terry Jones as well. The Monty Python Years: Cleese worked with Chapman extensively leading up to their success as Monty Python, first writing episodes for the “Doctor in the House”. Creative and lifestyle differences encouraged further collaboration, which inspired Cleese and Chapman to bring in Gilliam, Jones, and Idle. Thus, Monty Python was born. “Monty Python’s Flying Circus” had a successful four-season run from October of 1969 to December of 1974 on BBC Television. Cleese made the decision to quit the Circus after its third season. Cleese’s famous contributions include “The Ministry of Silly Walks”, portrayals of stressed-out intellectual loonies, and his “Sergeant Major “character. After the Circus, Cleese remained friendly with the now famous group of writers/comedians. The group began its efforts writing feature films, which include “Monty Python and the Holy Grail”, “Monty Python’s Life of Brian”, as well as “Monty Python’s The Meaning of Life” — all of which are considered topflight comedies and hugely influential when it came to inspiring up-and-coming writers and comedians. Film and TV Career: Cleese would go on to co-write the beloved TV series “Fawlty Towers” with his wife, Connie Booth — both ended up starring in the show. Cleese also starred in “Clockwise” and “A Fish Called Wanda”. His other film and TV credits include “George of the Jungle”, “The Out-of-Towners”, “The World Is Not Enough”, “Harry Potter and the Philosopher’s Stone”, “Harry Potter and the Chamber of Secrets”, “Die Another Day”, “Charlie’s Angels: Full Throttle”, “Cheers”, and “Whoops Apocalypse”. Personal Life: Cleese has been married four times, most recently to Jennifer Wade in 2012. He has two children. When Cleese divorced his third wife Alyce Faye, in 2008 after 16 years of marriage, the comedian was ordered to pay her a $20 million settlement plus $1 million a year through 2016. Philanthropic Efforts and Politics: Cleese joined forces with other members of the Python gang once again in order to assist such charitable endeavors and causes as Amnesty International, and Cleese himself has been a long-standing supporter of the Liberal Democrats. In 2008, Cleese expressed his support for presidential candidate Barack Obama and even offered up his services to the former commander in chief as a speech writer. He also has an asteroid (9618 Johncleese) named in his honor. Cleese is also well-known for his love of lemurs. Cleese was named Provost’s Visiting Professor at Cornell University and has also served as Andrew D. White Professor-at-Large (1999-2006). In 2016, Cleese went on record and criticized Donald Trump’s US Presidential run, describing the former president early on as “A narcissist, with no attention span, who doesn’t have clear ideas about anything and makes it all up as he goes along”. Cleese himself has been known to make occasional appearances on the Cornell campus that are always well-received. Real Estate: In 1998 John paid $3.443 million for a home in Montecito, California. He listed the home for sale in 2008 for $11 million. He ultimately accepted $5.1 million in 2010. In 1999 John paid an undisclosed amount for two side-by-side parcels in Montecito that combined into a 15+ acre equestrian ranch. He listed the home for sale in July 2007 for $28 million. In July 2008 he accepted a $16 million offer from cellular technology billionaire Craig McCaw. In 2018 John announced he was leaving England after being disappointed by Brexit. He listed a home near Bath for $3 million and and a London apartment for $1.75 million. At the time he announced his intention to relocate to the Caribbean island of Nevis.
