Famous Jamaican Scientists Dreamers Among Us – Prof. Louis Grant, 1913 – 1993

The saying “we likkle but we tallawah” can be applied to many aspects of Jamaican life, not the least of which is Jamaica’s contribution to world science. This article, the first in a two-part series featuring Jamaican scientists, considers the work of Professor Louis Grant, microbiologist, one of those whose work had immense local and international impact.

PROF. LOUIS GRANT, M.D., C.H., M.P.H., DIP BACT., FAPHA, F.C. PATH, F.A.A.N. (1913-1993)
A microbiologist and pathologist, Prof. Louis Grant was affiliated with the University of the West Indies for 20 years where he achieved the highest academic honour, being named professor emeritus in microbiology. Young Louis Grant was surrounded by science from an early age ­ born in Vere, Clarendon in 1913, his father worked in a chemical laboratory at the Appleton Estate. As a student, Grant showed promise and received the Vere Trust scholarship to attend Jamaica College. He went on to Edinburgh University in Scotland and later specialised in tropical microbiology at the London School of Tropical Medicine and Hygiene. Prof. Grant then returned to Jamaica serving his country as a medical doctor, microbiologist and pathologist.

TUBERCULOSIS
In the 1940s Dr. Grant dreamed of a Jamaica with less disease and he decided to focus on tuberculosis ­ a disease then plaguing the island. He asked the World Health Organisation (WHO) and UNICEF for a grant to begin an inoculation campaign amongst Jamaican children. Joined by Dr. Ronald Lampart, Dr. Grant completed a mass vaccination that is credited with helping to break the cycle of infection and halt the spread of the dreaded disease.

1964: Prof. Louis Grant speaking at a luncheon held by the Society of Medical Technologists (UWI) at the Flamingo Hotel in honour of his recent appointment to the new chair of Microbiology at UWI.

Groundbreaking Research On Three Diseases  
During the decade of the 1960s, Dr. Grant became a full professor of microbiology at the University of the West Indies, Mona. Three diseases came to his attention. Two affected the island’s general population and one its horse population.

LEPTOSPIROSIS
In the early 1960s many Jamaicans began to fall ill with severe fevers. Some, who seemed otherwise healthy, soon died. Through intensive research Dr. Grant discovered that this disease was spread through contact with the urine of infected animals. Rats were immune to it and therefore major carriers of the virus. Dr. Grant deduced that
rats tend to urinate after eating in kitchens and this way people would consume food on which rats might have already urinated. There is no cure for viruses, the most doctors can do is make the patient comfortable while the body fights off the infection. The leptospirosis virus, if not rejected by the body immediately on contact, would then enter the blood stream, multiply and possibly lead todeath. Dr. Grant quickly spread the word, cautioning against rats entering kitchens and the danger of leaving food exposed. This public education campaign helped contain the spread of the disease, outbreaks of which have since been controlled.

EQUINE ENCEPHALITIS
In the mid-1960s, reports of a disease afflicting horses on the eastern side of the island began to surface. Prof. Grant instituted quarantine on the movement of horses, donkeys and mules from that region. After much laboratory investigation he discovered that the horses were suffering from a virus known as equine encephalitis, which could not be spread to humans but could cause great damage to Jamaica’s horse population. He recommended further measures for containment, thereby preventing the spread of the virus and the ruination of Jamaica’s billion-dollar horse industry. He also acquired a new title ­ the horse saviour.

1968: Prof. Louis Grant, centre, vice president of Jamaica Blue Cross, addressing a meeting of the Board of Trustees of the health plan at headquarters, Hope Road. Members, clockwise, are Dr. B.A. Shoucair, Dr. M.W. Minott, Dr. Horace Penso, Dr. C.C. Jones, Mr. Barrington Yee, Mr. Sydney Anderson, Dr. B.W. Minott, Mr. Hector White, Mr. Douglas Kerr and Mr. Eric Richards.

DENGUE FEVER
In the late 1960s Jamaicans began to suffer from a strange fever. Dr. Grant identified it as the dengue virus and concluded after much research that it was transmitted via the aedes aegypti mosquito ­ the same mosquito that carries the deadly yellow fever virus. This led to another public education campaign and the beginning of a research effort on the study of arboviruses (viruses spread by blood-sucking insects) at UWI.  

RETIREMENT
In the early 1970s Prof. Grant retired from the University of theWest Indies and moved to Canada. From 1974 to 1977 he served as the Associate Medical Officer of Health for the Niagara Regional Health Unit. From 1977 to 1984, he acted as the Medical Officer of Health for the Haldimand-Norfolk Health Unit. Throughout the decade he spent in Canada, Dr. Grant became an active member of the Ontario Public Health Association (OPHA) and the Canadian Public Health Association (CPHA), a community activist and an advocate for social justice. He gained increasing recognition and was eventually able to attract large measures of funding to fulfil his lifelong dream of establishing a public health clinic for low income Jamaicans. He returned to Jamaica, bringing many international scientists with him who served at reduced or no cost. His clinic, The Foundation for International Self-Help (FISH), opened in Papine in 1985.
Prof. Grant died in Jamaica in 1993, leaving behind a wife and four children and ending a career that spanned 50 years in public service. He had authored over 90 scientific publications in microbiology and public health and received the Gleaner Special Award and the Pelican Award in 1985. Prof. Grant is remembered as the father of Jamaican microbiology. In 1996, an award in the form of a $1000CD scholarship and one-year membership in OPHA was established by the OPHA in his honour. The award supports the postgraduate education of an individual enrolled in a post-graduate programme in community or public health.

  8. Can we please have a movie or documentary about this man in jamaica? I’m a very sad young jamaican that is tired of hearing about singers only. Singers are great artists they teach you while you listen but this man has saved lives times 3 and he is swept under the rug.
