History
Solar urticaria was first identified by P. Merklen in 1904. Just a year later, in 1905, Ward became the first to induce urticaria through exposure to the sun in a controlled environment. The first documented case came in Japan in 1916. The name "solar urticaria" was proposed in 1923. In 1928 urticaria was induced for the first time. This was carried out by phototesting with increasing amounts of radiation of varying wavelengths. In 1942 the disease was passively transferred to normal volunteers using serum from patients with solar urticaria.

Famous quotes containing the word history:
“There is no history of how bad became better.”
—Henry David Thoreau (1817–1862)
“We have need of history in its entirety, not to fall back into it, but to see if we can escape from it.”
—José Ortega Y Gasset (1883–1955)
“There is nothing truer than myth: history, in its attempt to “realize” myth, distorts it, stops halfway; when history claims to have “succeeded” this is nothing but humbug and mystification. Everything we dream is “realizable.” Reality does not have to be: it is simply what it is.”
—Eugène Ionesco (b. 1912)
