Fragment of the Canyon Diablo iron meteorite. Patterson developed the uranium—lead dating method into lead—lead dating and, by using lead isotopic data from the Canyon Diablo meteorite , he calculated an age for the Earth of 4. He graduated from Grinnell College with a bachelor degree in chemistry in There, he met his future wife, Lorna McCleary. For graduate school, they both attended the University of Iowa, where he was awarded an M. Both were then sent to work on the Manhattan Project, first at the University of Chicago and then at Oak Ridge, Tennessee , where he encountered mass spectrometry. After World War II, the Pattersons returned to Chicago, where his wife Lorna took a research job as an infrared spectroscopist to support Patterson while he worked for his Ph. After a postdoctoral year at Chicago, Patterson moved with Brown to the Division of Geology at the California Institute of Technology in , as founding members of its geochemistry program. He became a full professor in and reached emeritus status in

After graduating with a degree in chemistry , Patterson completed his Ph. Using a newly developed form of lead dating, Patterson succeeded in his mission, giving us the estimate, 4. Patterson unwittingly discovered that modern industrial output, mainly car exhaust fumes, were adding devastatingly large amounts of lead to the air, at a rate that was sure to eventually cause widespread lead poisoning.
Patterson took on powerful oil and auto industry heads with a financial interest in silencing his work, and succeeded in demonstrating to the world the gravity of this problem. Patterson passed away in , at the age of Patterson can be found in the Grinnell College Libraries’ online catalog.

Adventures of Clair Patterson
Professor Mervyn Paterson is a geophysicist who has led Australian research into rock mechanics and pioneered instrument development over the last fifty years. He was born in South Australia in into a family of wheat farmers. He began his career at the CSIR Division of Aeronautics working on the physics of metal fatigue, a foundation which shaped his entire career. I think it is fair to say that Mervyn Silas Paterson is Australia’s leader in research into rock mechanics under a range of laboratory and geological conditions.

Tens of millions of teens have been taught the lie that evolution is a fact. It s not.
How Old Is Earth?
At around the same time that Arthur Holmes published his ideas for the age of the Earth, Harrison Brown, a professor at the University of Chicago, was developing a new method for counting lead isotopes in igneous rocks. Brown thought this method of counting was incredibly tedious but very easy, so he assigned it to Patterson as his dissertation project in Prior to beginning his research, Patterson had worked on the Manhattan Project during World War II, showing that, by the time he began his research, he had much experience in the field.
The main problem with using this method of dating was that Patterson needed ancient rocks that contained crystals bearing both uranium and lead.
Patterson developed the uranium–lead dating method into lead–lead dating. Using his technique, Patterson was able to calculate the age of the Earth at .
Photo courtesy Caltech Archives. The impact of geochemist Clair C. Research to determine the age of the earth eventually turned geochemist Clair C. By the time Patterson was 31, his contribution to knowledge surpassed what most people can claim in a lifetime. Pursuing that achievement revealed the troubling specter of a poisoned modern environment and prompted even more important work. The Clean Air Act and a global effort to remove lead from gasoline and other products grew out of the awareness his subsequent research and advocacy created.
Lead is a neurotoxin, affecting the brain in ways that diminish IQ, disrupt neural communication, and decrease the size of the prefrontal cortex, inhibiting impulse control and motor functions. But because it was cheap and malleable—and because slaves and other laborers had the most direct contact—lead remained essential to many amenities. They used it in cooking pots and even to sweeten wine.
In the early 20th century, its increased use in consumer products was marketed as a great benefit. Tetraethyl lead started to be used as a gasoline additive in the s. The weapons-grade hazard it presented became horrifyingly prevalent.
The Clean Room
Clair Patterson, an American geochemist, was born June 2, Patterson is one of the most unsung of the great 20th-century geologists. His specialty was geochronology—the dating of the Earth. Ever since , when radiometric dating was first proposed, the basic technique for dating the Earth had been the same: compare the amount of uranium in a rock with the amount of its radioactive decay byproduct, a specific isotope of lead. The more lead and the less uranium , the older the rock.

As nature coerces us into a state of lockdown, a forced slowing down brought forth by the coronavirus pandemic, people across the world are rethinking not just their means of living, but also what will be the future of our planet and the various systems and practices that knowingly or unknowingly govern our everyday lives. Artists who have always been known to respond to the flux of times are no different. In recent times, many have been increasingly experimenting with sustainable materials, eco-friendly practices and concepts.
Anne Patterson, a New York -based artist, theatre and set designer and sculptor, it seems, rode the wave of sustainable art right before everything came to a halt.
Patterson developed the uranium-lead dating method into lead-lead from the Canyon Diablo meteorite, he calculated an age for the Earth of.
The scientist who discovered the age of the Earth also helped end the use of lead in gasoline and other products in the United States. Sunday night’s episode April 20 of ” Cosmos: A Spacetime Odyssey ” explored the life of Clair Patterson, a geochemist who pinpointed Earth’s age for the first time and also uncovered a secret: Lead contamination is a major and potentially deadly problem. The newest episode of “Cosmos,” called “The Clean Room,” takes viewers on a tour of Patterson’s work and the industry that fought him as he tried to learn more about lead and its harmful effects.
Patterson’s work initially focused on the Earth’s age. Many scientists had tried to date the age of the planet before Patterson, coming up with different numbers, but he did something different during his experiments. He was enlisted to measure the amount of lead in zircon crystals from a fragment of a meteorite — a leftover space rock from the dawn of the solar system — to better understand the age of the Earth.
Eventually, Patterson moved to the California Institute of Technology, where he created the first scientific clean room to try to get a proper reading on his crystals. He was finally able to measure how much lead was actually in the rock, one whose age had already been established. Now, at last, Patterson was ready to tackle the iron meteorite.

This value is derived from several different lines of evidence. Unfortunately, the age cannot be computed directly from material that is solely from the Earth. There is evidence that energy from the Earth’s accumulation caused the surface to be molten.

He was queasy, not out of his mind. But on a mild October night in , shortly after Dymock groggily tucked himself into bed, something within him snapped. Like a man possessed, Dymock rose, fumbled through the dark, opened his window, and leapt into his garden. Hours later, a passerby discovered him lying in the dirt, still breathing. He was hurried to a hospital.
Many of his coworkers were acting erratically too. Take William McSweeney. One night that same week, he had arrived home feeling ill. By sunrise, he was thrashing at phantoms.
The Most Important Scientist You’ve Never Heard Of
Planet Earth doesn’t have a birth certificate to record its formation, which means scientists spent hundreds of years struggling to determine the age of the planet. So, just how old is Earth? By dating the rocks in Earth’s ever-changing crust, as well as the rocks in Earth’s neighbors, such as the moon and visiting meteorites, scientists have calculated that Earth is 4. Related: How Big is Earth? Scientists have made several attempts to date the planet over the past years.
They’ve attempted to predict the age based on changing sea levels, the time it took for Earth or the sun to cool to present temperatures, and the salinity of the ocean.
In geochemistry, he is best known for first establishing the true age of the Earth and solar system at billion years, a date the accuracy of.
Claire C. Patterson’s biographer and peer George H. Tilton described him as energetic, innovative, determined and “modest about his own accomplishments. He received many scientific awards, and an asteroid discovered in is named in his honor. A peak in the Queen Maude Mountains in Antarctica also carries his name. Long before anyone else, Claire Patterson was warning the world about the dangers of lead poisoning.
The scientist saved countless lives when he pushed for the elimination of lead from gasoline, paint and food containers as well as water pipes, solder, pesticides, foils and aerosols. Patterson, long associated with the California Institute of Technology, made his mark in another significant way: He was the first person to accurately determine the age of the Earth at 4.
