This is a week of Days—international days to mark events, or create awareness about different themes and issues. 22 May is the International Day for Biological Diversity, and 23 May celebrates Turtles–one of the millions of species

that are part of the incredible tapestry of biodiversity.
This took me to revisit some of the teaching-learning material on these themes that we developed in CEE, among them, an Educator’s Manual on Turtles. Going through it I rediscovered the inspiring story of Archie Carr–the Turtle Man.
Archie Fairly Carr Jr., was an American zoologist whose studies unraveled many mysteries about giant sea turtles, and whose writings and conservation efforts have helped to save sea turtles from near extinction.
Archie Carr was born on June 16, 1909, in Alabama, where his father was a Presbyterian minister and his mother a piano teacher. It was his father who instilled in him his love for nature. The backyard of their home was filled with cages of snakes, frogs, lizards, and turtles that the young Archie collected. As a child he also developed a keen ear for language and music. In later years he further developed these language skills which led him to master several languages, and his work in collecting dialects from the Caribbean area and east Africa where he travelled and worked.
Archie Carr originally went to the University of Florida to study English but was diverted to biology by a professor who recognised the young student’s love for nature. In 1937 he became the first to be granted a PhD in zoology by the University. And it was his alma mater that became his lifelong academic home; he was associated with the University for more than fifty years.
Carr was a true, and early, ecologist of his times. While his early training was in taxonomy and evolutionary biology, he combined this with his wide knowledge of zoology, botany, soils, geology, history, and cultural anthropology, and he showed his students the need to weave together all of these disciplines to begin to understand the subject matter of ecology. This breadth of understanding and perspective also permeated his writings which beautifully combined the different strands.
Above all, Archie Carr was a great biologist. His early descriptive studies of turtles set the standard of quality in the field of natural history. He published his first paper on sea turtles in 1942, but it was not until he wrote his classic Handbook of Turtles (1952) that he began to focus his research on sea turtles. He described his early discoveries about the plight of sea turtles in his book The Windward Road particularly in his chapter The Passing of the Fleet, which was a call to arms and resulted in global efforts to conserve sea turtles from extinction
As he focused on sea turtles, Carr moved toward ecology and behaviour, although his work always retained a taxonomic and evolutionary perspective. His decades-long research at the research station at Tortuguero in Costa Rica, enabled him to initiate one of the longest lasting and most intensive studies of an animal population that has ever been done. Almost all of these studies have significance for conservation; Archie Carr was a conservation biologist long before the field was recognized.
Carr’s book The Windward Road published in 1959 deeply touched a newspaperman Joshua Powers. He sent copies of the book to twenty friends with an invitation to join a new organisation called The Brotherhood of the Green Turtle; this grew into The Caribbean Conservation Corporation, and later the Sea Turtle Conservancy, which became an international force for the preservation of sea turtles.
Like many of his generation Carr was at one time an avid hunter, but he gave this up after his travels in Africa. This change he described in his book Ulendo: Travels of a Naturalist in and out of Africa, in 1964. And also, like many hunters turned conservationists, such as Jim Corbett in India, Carr wrote extensively and evocatively about wildlife and nature. ”It was the lion song, and I sat quiet to learn it, as you learn the trill of a tree toad, or how an alligator goes. And though there may have been little real song in the sound, it came in strong and lonely through the whisper of the mist; and to me, at the time, it seemed to tell of an age being lost forever.”
He was far from the stereotype of a ‘scientist’ whose highly technical and academic language could be understood only be a select band of fellow scientists. He combined his original academic interest in English, and his love for the language, with his passion for biology by writing 11 books, several of which won top awards were a model of authoritative yet lively scientific writing.
His colleagues remember him for his sense of humour that often included practical jokes, and which peeped through his writing. “I like the look of frogs, and their outlook, and especially the way they get together in wet places on warm nights and sing about sex”.
His wife once jokingly told him “You’ve done a lot for turtles.” To which he replied “They’ve done a lot for me too.”
Professor Carr, died at his home on May 21, 1987. At the time of his death, he was the world’s leading authority on sea turtles.
The world that Archie Carr explored and wrote about has changed a lot today. Yet the sea turtles remain, thanks to the painstaking pioneering work, passion and life-long mission of this brilliant scientist and inspiring human being.
Today is a good day to remember his words, “For most of the wild things on earth, the future must depend on the conscience of mankind.”

Florence was also one who shook up systems and brought in systemic changes. She battled with entrenched bureaucracies most of her working life, in order to bring about these changes. She was aware that it would be difficult to convince decision makers of the need for change, and maybe out of this requirement was born what is today counted as her major contribution to statistics—the first infographics ever made. The best-known of the infographics she invented are what are called the “coxcomb” diagrams, understandable by even the public. ‘The coxcomb is similar to a pie chart, but more intricate. In a pie chart the size of the ‘slices’ represent a proportion of data, while in a coxcomb the length which the slice extends radially from the center-point, represents the first layer of data. The specific organization of Nightingale’s chart allowed her to represent more complex information layered in a single space. In her coxcomb during the Crimean War, the chart was divided evenly into 12 slices representing months of the year, with the shaded area of each month’s slice proportional to the death rate that month. Her color-coding shading indicated the cause of death in each area of the diagram.’*
Polio was a dreaded disease in the early 20th century. It left death in its wake, but even more, it paralysed. Till date, there is no cure for polio, and the only defence is vaccination. Jonas Salk rightly deserves the credit for the polio vaccine, but there were two women, without whose work things would not have happened as they happened, when they happened. One was Dr. Isabel Morgan of Johns Hopkins University, whose work was a turning point in understanding host immunity to polio and on use of killed-virus (vs. live-virus) as the basis of vaccines for this disease. The other was Dr. Dorothy Horstmann of Yale and her team, whose work is said to have paved the way for oral polio vaccines.

cutta, but Bangalore was also Sir Raman’s ‘karma bhoomi’, in that he worked at the Indian Institute of Science from 1933 till his retirement in 1948, after which he founded the Raman Research Institute in the city, and continued working there till his death in 1970.

January 4 was also the day when Profs Abhijit Banerji and Esther Duflo were in conversation with Manish Sabarwal at the Bangalore International Center, and demystified RCTs, or Randomized Control Trials, the body of work which got them their newly minted Nobels. RCTs are an experimental method to do research on developmental issues like education and poverty, to find what can really be effective to solve the problems, and hence can help policy making.
