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.

However, the two sides are not to be divided off; as long as men exist the history of nature and the history of men are mutually conditioned.”
—Karl Marx (1818–1883)
