Nelson Norman’s 2009 book, In Search of a Penguin’s Egg, worked its way to the top of my to-be-read pile and I found it a fascinating account of how he came to be sent, as a newly-qualified medical graduate doing his National Service, to Antarctica as a medical officer and voluntary general factotum to the Falkland Islands Dependencies Survey (FIDS) (now the British Antarctic Survey) at Halley Bay for the antarctic winter of 1959.
As part of his research activity he was asked by Sir Raymond Priestley, an Antarctic explorer in his younger days and former vice-chancellor of the University of Birmingham who was still active with FIDS, to obtain a series of Emperor Penguin embryos at 12-hour intervals over the first ten days of incubation:
…he told me that 4 or 5 kilometres from Halley Bay, there was a rookery of emperor penguins…He told me that these birds were close to being the most primitive species of bird and possibly the embryological link in the evolutionary chain between reptiles and birds. They were thus if great scientific importance. There was an anatomist at Charing Cross Hospital who was desperate to get a precisely timed series of emperor penguin embryos at twelve-hour intervals for ten days. He stressed the importance of this and asked me to secure them…Nor did he tell me that a previous attempt had been made during Scott’s last expedition and that only one man had survived—Apsley Cherry-Garrard.
Before his departure, Norman had a half-hour meeting with Dr Glenister of Charing Cross Hospital who repeated his requirement for the timed series of preserved embryos.
By ingenuity, dedication and fortitude—but not without danger during the Antarctic winter—Norman succeeded in bringing back the series of embryos. However, the reception of his embryos in London was less than enthusiastic:
…The taxi crossing London did not crash—as had been my recurring nightmare in Antarctica—neither was the enthusiastic Dr Glenister standing on the front steps to meet me. I was informed politely but rather coldly by a secretary that he was now the Professor of Anatomy and a a very busy man. I was, therefore, invited to leave the embryos and my report with a technician and basically just to go away. I did this rather reluctantly and unhappily, and I never heard anything more from Professor Glenister though I did think that he could at least have written a short note of thanks considering what we had gone through to produce the embryos. I enquired several times over the years and was persistently told by FIDS that the embryos were being worked on…Nearly fifteen years later when I was in a position to consider the matter further and was a research director myself I went to the British Antarctic Survey (as FIDS was known by that time), expressed my concern, and asked for my embryos back saying that I would find an interested embryologist and we would work them up between us. This was agreed but when it asked for the embryos, the Survey was told that a technician had accidentally disposed of them!
What an appalling way to treat a young scientist, was my thought as I read Nelson’s account. But the reason for writing this post is to remark that this sort of treatment of young scientists and technicians was by no means uncommon. I have known individuals who have worked hard to complete a task, only for the specimens or results to be ignored for weeks, months, years and, sometimes, for ever.
So why was Nelson launched on this ultimately worthless mission? The story is well known of how Edward Wilson, chief of the scientific staff of Scott’s final (1910-1912) expedition and who died with Scott and his party, had become convinced that by studying the embryonic development of the Emperor Penguin he could follow the evolutionary transition from reptiles to birds. In 1907, in his report on the 1901-1904 expedition in which the breeding cycle of this species was discovered, he wrote: The possibility that we have in the Emperor Penguin the nearest approach to a primitive form not only of penguins but of a bird, makes the future working out of its embryology a matter of the greatest importance. It was a great disappointment to us that although we discovered their breeding ground. and although we were able to bring home a number of deserted eggs and chicks, we were not able to procure early embryos by which alone the points of particular interest can be worked out. Obtaining embryos was Wilson’s aim when he set off in 1910.
The appalling conditions endured by Wilson, Henry Bowers and Apsley Cherry-Garrard in their search for the eggs are described by Apsley-Garrard in his book, The Worst Journey in the World. Three eggs survived the six-week, 65-mile return journey from Cape Crozier. The three men also survived this part of the expedition; Wilson and Bowers then died with Scott’s party. It would appear that Cherry-Garrard’s life was wrecked by the trauma of the whole expedition and its outcome.
The enthusiasm of the Natural History Museum for the receipt of Cherry-Garrard’s eggs in 1913 was a forerunner of the enthusiasm of Glenister for the arrival Nelson’s embryos. The account in The Worst Journey in the World of his encounter with the Museum’s officialdom is an example of British jobsworths at their finest. However, the 1911 embryos were worked on, first by Dr Richard Assheton FRS, lecturer in embryology at Cambridge who died in 1915, then by Professor Cossar Ewart FRS, professor of natural history in Edinburgh, who produced a report that can only be described as kindly and, finally, 20 years after their collection, by Charles Wynford Parsons FRSE (1901-1950) of the University of Glasgow. Parsons did not pull any punches: [the eggs] have not contributed much to the understanding of the embryology of penguins.

View of the Emperor Penguin Rookery at Cape Crozier by Edward Adrian Wilson
From his report of the 1901-04 Expedition |
Before moving to consider why, during the 1950s, the collection of Emperor Penguin eggs was considered to be of such importance to FIDS, what drove the enthusiasm of Wilson in the first place?
Two influences are said to have driven him. The first, which seems bizarre to the point of craziness when looked at now and perhaps even then, was the suggestion in a long paper by Mikhail Aleksandrovich Menzbier (1855-1935), professor of comparative anatomy in Moscow, that penguins had evolved separately from reptiles on a parallel evolutionary line to other birds. However, the argument that Wilson got his impetus from Menzbier does not quite stack up with his statement, The possibility that we have in the Emperor Penguin the nearest approach to a primitive form not only of penguins but of a bird. Wilson seemed to have the impression that the Emperor Penguin could be the most primitive of all birds which is not what Menzbier was arguing.
The second influence was, of course, recapitulation, the theory of Ernst Haeckel: ontogeny recapitulates phylogeny. The flaws in making this idea a law of nature are so well known that I will not repeat them. However, if true, the development of the Emperor Penguin should, if it were the most primitive bird, show it passing through a reptilian stage relatively late in development. That is what Wilson was hoping the results would decide.
Encouragement along the lines of a separate descent for penguins or for the Emperor Penguin being the primitive bird did not come from the Natural History Museum. W.P Pycraft in the same volume as Wilson’s report of the 1901-1904 expedition wrote:
All that can be gleaned from fossils, then, is that penguins have probably descended from birds which possessed full powers of flight, and this probability becomes converted into a certainty when the embryological evidence comes to be examined. But the question of the precise affinities of this group must still be regarded as an unsolved problem, the intense specialisation which these birds have undergone obliterating much of the necessary evidence.
However, Pycraft was clearly thinking along Haeckelian lines when he supported the collection of more embryos:
Some day another Antarctic Expedition will be sent out, when it is to be hoped that, so far as the penguins are concerned, special efforts will be made to secure the earlier nestling stages of the King, and the latter stages of the Emperor Penguin full-grown nestlings of the latter being especially needed; while of both species the early and middle embryonic stages are wanted. Ripe embryos will add but little of real value to our knowledge, since they differ but little of course from the newly-hatched nestling, and furthermore, several examples are among the spoils of the expedition herein concerned. A few adults of both species would certainly be useful if preserved entire, in spirit, or in ice.
Although ideas, often wrong, on the evolutionary history of penguins rumbled on, the notion that the Emperor Penguin was vital for the study of the origin of birds was well and truly dead by the 1950s. Also by then recapitulation had also been effectively demolished as a doctrine. So why did Sir Raymond Priestley push the importance of collecting a series of embryos to Nelson Norman? Was FIDS in some sort of time warp with its own unchanging research agenda, locked into continuing the unfinished research of dead antarctic heroes? The cynical might be tempted to suggest that some at FIDS were looking for reasons to use the Halley Bay base and its nearby penguin colony for biological research on the use it or lose it principle of government funding. However, since most of the research there was concerned with the physical environment and FIDS was taking over Halley Bay from the Royal Society which had established it for the International Geophysical Year in 1957-58, there may have been no need for a research excuse.
The request to Nelson seemed even more strange to me when I read (not in Norman’s book) that a series of Emperor Penguin embryos (16 from the primitive streak to hatching) had been collected by Bernard Stonehouse in 1949 and described by Glenister in a letter to Nature. Without providing quantitative data, Glenister stated that early penguin embryos (others had described Gentoo and Chinstrap penguin embryos) resemble early reptilian embryos more closely than do early chick embryos. The thought also occurred to me that since the Emperor and King penguins are closely related and, then and now, included in the genus Aptenodytes, why the insistence on Emperor embryos when King Penguins were readily accessible and available in abundance on South Georgia where whaling stations were maintained until the 1960s?
Finally, there is Professor Glenister who seemed less than keen to receive Norman’s embryos. Tony William Alphonse Glenister (1923-1998) was an embryologist at Charing Cross Hospital Medical School. He became Professor of Embryology, then of Anatomy. He was Dean of the Medical School from 1976 to 1984 and then Dean of the combined Charing Cross and Westminster school until 1989. A building is named after him at Imperial College, the final destination of these medical schools in the organisational reshuffles of the London colleges. He was President of the Anatomical Society in 1979-81; he wrote Anatomy and Physiology for Nurses.; he has 18 papers listed in PubMed, mainly on mammalian embryology. Recently, he has been identified as one of the referees who opposed the awarding of a grant to support the work of Edwards and Steptoe on human fertilization in vitro (IVF). In that he was by no means alone.
I do not know how Glenister became involved with the penguin embryos. One explanation is that he was drawn in by FIDS to work on the embryos brought back by Stonehouse. Glenister wrote a report for FIDS entitled, The Emperor penguin, Aptenodytes forsteri Gray: II Embryology. I have not seen this report but I think it is a fuller version of the letter to Nature. His work on the embryos was descriptive and I can only assume that in sending Norman for more he felt that there were gaps to be filled. Whether he then lost interest in the topic or somebody had a quiet word with him that the work was of insufficient scientific importance, whether he became bogged down in university administration or whether his role in the Territorial Army increased, I do not know. Whatever the reason there is no doubt that Norman, quite rightly, felt highly aggrieved by his reception on delivering the embryos, by the lack of contact with Glenister and, later, by their destruction.
Sadly, Nelson Norman’s and Cherry-Garrards’s experiences when they returned were not, and may still not be, uncommon. As to the wider question, of why FIDS persisted in pursuing an outdated notion (hypothesis would be too strong a word), a historian delving into the archives may be able to judge. However, such behaviour would not be unusual for a British government department or agency. Research agendas unchallenged by effective external review were alive and well into the 2000s, to my certain knowledge; some still may be.
The appraisal of Wilson’s pursuit of Emperor Penguin embryos must not detract from his and the other explorers’ achievements in the Heroic Age of Antarctic Exploration. An incredible amount of work was done in all the relevant fields of science; important discoveries emerged from each expedition. The observations and collections they made would have been arduous in a temperate environment; in an antarctic winter with temperatures as low as -61°C survival alone was a triumph.

Antarctica stands head and shoulders above anywhere else in the world I have visited. The scenery, the air, the ice, the mammals and the birds have to be seen and heard to be believed. I can see why the explorers were drawn back.
Our view back to the ship from Jougla Point, Wiencke Island, Port Lockroy in 2005. The furthest south we reached in the Lemaire Channel was still 1722 statute miles from the South Pole.
The ship is the MV Lyubov Orlova which hit the headlines recently (Ghost ship carrying cannibal rats 'may have sunk’, for example) is either drifting in the Atlantic or has sunk.
