George C. Clerk

George C. Clerk is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand George C. Clerk rather than just read about it. In short: George Carver Clerk, (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.

Key takeaways

  • George C. Clerk belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect George C. Clerk to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of George C. Clerk from memory before moving on to harder problems.

Reference excerpt

George Carver Clerk, (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 administrator 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 the University of London, then the parent institution of the university college. He received his bachelor's degree in botany with first-class honours and winning the first prize as the best graduating student in botany. 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. The pioneer British plant pathologist, Ronald Karslake Starr Wood (1919 – 2017) also supervised his research in London.

Worked examples

Example 1 — a first encounter with George C. Clerk

Start with the simplest possible case. Write down what George C. Clerk 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 George C. Clerk 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 George C. Clerk 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 George C. Clerk

In research
George C. Clerk 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 George C. Clerk 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
George C. Clerk is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1931 births, 2019 deaths, 20th-century Ghanaian botanists, so understanding it makes those chapters shorter.
In everyday life
Look for George C. Clerk 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.
