Alfred Wegener, in full Alfred Lothar Wegener, (born November 1, 1880, Berlin, Germany—died November 1930, Greenland), German meteorologist and geophysicist who formulated the first complete statement of the continental drift hypothesis.
Was Alfred Wegener a doctor?

What was Alfred Wegener claim?
About 300 million years ago, claimed Wegener, the continents had formed a single mass, called Pangaea (from the Greek for "all the Earth"). Pangaea had rifted, or split, and its pieces had been moving away from each other ever since.
How did Alfred Wegener impact the world?
Lived 1880 – 1930. Alfred Wegener proposed the theory of continental drift – the idea that Earth's continents move. Despite publishing a large body of compelling fossil and rock evidence for his theory between 1912 and 1929, it was rejected by most other scientists.
What was Alfred Wegener's childhood like?
Alfred Wegener was born in Berlin in 1880, where his father was a minister who ran an orphanage. From an early age he took an interest in Greenland, and always walked, skated, and hiked as though training for an expedition. He studied in Germany and Austria, receiving his PhD in astronomy.
34 related questions foundWhat causes Wegener's death?
The most common causes of death in the first year after diagnosis of WG were: infection 9 (32%) out of 28; active vasculitis 5 (17.9%) out of 28; and renal failure 5 (17.9%) out of 28.
How long can you live with Wegener's disease?
Prior to recognizing effective therapy in the 1970s, half of all patients with this illness died within 5 months of diagnosis. Today, more than 80% of treated patients are alive at least eight years later. For many people with GPA, long term survival has been seen with many able to lead relatively normal lives.
Can Wegener's disease be cured?
There is no cure for Granulomatosis with polyangiitis, but the long-term outlook, with appropriate medical treatment, is very good. In many cases, prompt treatment can bring about a remission, which means the person has no signs or symptoms of the disease.
How do you get Wegener's?
The cause of granulomatosis with polyangiitis isn't known. It's not contagious, and there's no evidence that it's inherited. The condition can lead to inflamed, narrowed blood vessels and harmful inflammatory tissue masses (granulomas).
What did other scientists think of Alfred Wegener's theory?
Other scientists did not believe Alfred Wegener's theory of continental drift because they did not see any way that continents could move through the oceanic crust and the mantle, nor did they see evidence that this had happened. They weren't aware of anything that could cause continents to move.
Was Alfred Wegener's theory accepted?
Wegener first presented his idea of continental drift in 1912, but it was widely ridiculed and soon, mostly, forgotten. Wegener never lived to see his theory accepted—he died at the age of 50 while on an expedition in Greenland. Only decades later, in the 1960s, did the idea of continental drift resurface.
How did Alfred Wegener contribute to the theory of plate tectonics?
Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of "continental drift." Wegener proposed that the continents plowed through crust of ocean basins, which would explain why the outlines of many coastlines (like South America and Africa) look like they fit together like a puzzle.
Why did scientists reject Wegener's theory?
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
What did Wegener wrong?
The greatest problem facing Wegener was the lack of direct evidence for the movements of continents (no GPS at the time!) and no mechanism was known to be powerful enough to move entire continents.
What foods should I avoid with vasculitis?
It is important to adhere to this regime. If you do not need a special diet, you should aim to cut down on starchy foods – bread, potatoes, rice and pasta, replacing these with fresh fruit and vegetables. You should also avoid processed food and grain fed meat.
What is the survival rate for Wegener's granulomatosis?
The 1- and 5-year survival rates were 87.8 and 71.6% for all patients, but lower for MPA (80 and 55%) compared with WG (95 and 83%; P = 0.001), although the difference was not significant in the multivariate analysis. The SMR was 2.77 (95% CI 2.02, 3.71) for all patients.
Does Wegener's cause hair loss?
We believe that the pilose follicle is another organ which nay be affected in Wegener's granulomatosis by a vasculitis of the scalp vessels; and although we did not perform a scalp biopsy, it seems likely that this disease might have caused the patient's hair loss.
How long does it take for Wegener's to go into remission?
With current induction strategies using cyclophosphamide (CYC), rituximab (RTX) or methotrexate (MTX), more than 90 percent of patients are able to achieve remission. Once remission is achieved, typically after three to six months of therapy, patients are transitioned to maintenance medications.
How serious is Wegener's granulomatosis?
Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis, is a rare and life-threatening disorder that restricts the blood flow to several organs, including the lungs, kidneys, and upper respiratory tract. It is a type of vasculitis, an inflammation and injury to the blood vessels.
Is Wegener's disease painful?
Skin lesions may or may not be painful. Some affected individuals may have painfully cold fingers and toes in response to cold (Raynaud's phenomenon) caused by lack of blood flow to these areas. Sometimes, this is severe enough to cause tissue death (gangrene) of the tips of the fingers and toes.
Can Wegener granulomatosis affect the brain?
Abstract. The involvement of the central nervous system in case of Wegener granulomatosis (WG) is infrequent and usually leads to cranial nerve abnormalities, cerebrovascular events, and seizures. Meningeal involvement is quite rare and usually is due to the spreading from adjacent disease in the skull base.
How does Wegener's affect the lungs?
Wegener's granulomatosis is a systemic vasculitis that primarily involves the upper and lower respiratory tracts and kidneys. Pulmonary Wegener's granulomatosis can present with multifocal lung involvement or solitary lung lesions with no evidence of extrapulmonary disease.
Is Wegener's disease fatal?
Introduction: Wegener's granulomatosis (WG) is a potentially fatal condition with remissions and high relapses rates.
