Jacob Bronowski

Jacob Bronowski was a British mathematician and biologist of Polish-Jewish origin. He is best remembered as the presenter and writer of the 1973 BBC television documentary series, The Ascent of Man.

In 1950, Bronowski was given the Taung child's fossilized skull and asked to try, using his statistical skills, to combine a measure of the size of the skull's teeth with their shape in order to discriminate them from the teeth of apes. Work on this turned his interests towards the human biology of humanity's intellectual products.

In 1967 Bronowski delivered the six Silliman Memorial Lectures at Yale University and chose as his subject the role of imagination and symbolic language in the progress of scientific knowledge. Transcripts of the lectures were published posthumously in 1978 as The Origins of Knowledge and Imagination and remain in print.

He first became familiar to the British public through appearances on the BBC television version of The Brains Trust in the late 1950s. His ability to answer questions on many varied subjects led to an offhand reference in an episode of Monty Python's Flying Circus where one character states that "He knows everything." However Bronowski is best remembered for his thirteen part series The Ascent of Man (1973), a documentary about the history of human beings through scientific endeavour. This project was intended to parallel art historian Kenneth Clark's earlier "personal view" series Civilisation (1969) which had covered cultural history.

During the making of The Ascent of Man, Bronowski was interviewed by the popular British chat show host Michael Parkinson. Parkinson later recounted that Bronowski's description of a visit to Auschwitz—Bronowski had lost many family members during the Nazi era—was one of Parkinson's most memorable interviews.

Jacob Bronowski married Rita Coblentz in 1941. The couple had four children, all daughters, the eldest being the British academic Lisa Jardine and another being the filmmaker Judith Bronowski. He died in 1974 of a heart attack in East Hampton, New York a year after The Ascent of Man was completed, and was buried in the western side of London's Highgate Cemetery, near the entrance.


“The poem or the discovery exists in two moments of vision: the moment of appreciation as much as that of creation; for the appreciator must see the movement, wake to the echo which was started in the creation of the work. In the moment of appreciation we live again the moment when the creator saw and held the hidden likeness. When a simile takes us aback and persuades us together, when we find a juxtaposition in a picture both odd and intriguing, when a theory is at once fresh and convincing, we do not merely nod over someone else's work. We re-enact the creative act, and we ourselves make the discovery again......Reality is not an exhibit for man's inspection, labeled: "Do not touch." There are no appearances to be photographed, no experiences to be copied, in which we do not take part. We re-make nature by the act of discovery, in the poem or in the theorem. And the great poem and the deep theorem are new to every reader, and yet are his own experiences, because he himself re-creates them. They are the marks of unity in variety; and in the instant when the mind seizes this for itself, in art or in science, the heart misses a beat.”

“Dream or nightmare, we have to live our experience as it is, and we have to live it awake. We live in a world which is penetrated through and through by science and which is both whole and real. We cannot turn it into a game simple by taking sides.”

“This is the concentration camp and crematorium at Auschwitz. This is where people were turned into numbers. Into this pond were flushed the ashes of some four million people. And that was not done by gas. It was done by arrogance. It was done by dogma. It was done by ignorance. When people believe that they have absolute knowledge, with no test in reality, this is how they behave.”

“And when we describe it as I shall do, it becomes plain that imagination is a specifically human gift. To imagine is the characteristic act, not of the poet's mind, or the painter's, or the scientist's, but of the mind of man.”

“The richness of human life is that we have many lives; we live the events that do not happen (and some that cannot) as vividly as those that do; and if thereby we die a thousand deaths, that is the price we pay for living a thousand lives.”

“It's said that science will dehumanize people and turn them into numbers. That's false, tragically false. Look for yourself. This is the concentration camp and crematorium at Auschwitz. This is where people were turned into numbers. Into this pond were flushed the ashes of some four million people. And that was not done by gas. It was done by arrogance, it was done by dogma, it was done by ignorance. When people believe that they have absolute knowledge, with no test in reality, this is how they behave. This is what men do when they aspire to the knowledge of gods.Science is a very human form of knowledge. We are always at the brink of the known; we always feel forward for what is to be hoped. Every judgment in science stands on the edge of error and is personal. Science is a tribute to what we can know although we are fallible. In the end, the words were said by Oliver Cromwell: "I beseech you in the bowels of Christ: Think it possible you may be mistaken."I owe it as a scientist to my friend Leo Szilard, I owe it as a human being to the many members of my family who died here, to stand here as a survivor and a witness. We have to cure ourselves of the itch for absolute knowledge and power. We have to close the distance between the push-button order and the human act. We have to touch people.”

“The values by which we are to survive are not rules for just and unjust conduct, but are those deeper illuminations in whose light justice and injustice, good and evil, means and ends are seen in fearful sharpness of outline.”

“The act of imagination is the opening of the system so that it shows new connections. Every act of act of imagination is the discovery of likenesses between two things which were thought unlike. An example is Newton’s thinking of the likeness between the thrown apple and moon sailing majestically in the sky. Hence, the ‘discovery’ of the laws of gravity.”

“It is important that students bring a certain ragamuffin, barefoot irreverence to their studies; they are not here to worship what is known, but to question it.”
