Raymond de Dalmas (5 February 1862 - 4 February 1930) was a French voyager, arachnologist, [1] and ornithologist.
He was raised in Croatia. During his youth he visited many parts of Europe, Algeria and Iceland. He was only 21 years old when in 1882 he undertook a westward journey around the world.
On September 5, 1882 he left with a friend doctor of Glasgow and arrived in New York on September 14. He traveled across the continent via the Niagara Falls, Chicago, Cheyenne, the Rockies, Ogden, Salt Lake, the Sierra Nevada and San Francisco, where he embarked an American liner Le Gaëlic whose crew was entirely Chinese and arrived on October 19 in Yokohama.
Both entered Tokyo where Dalmas obtained from Governor Tricou the authorization to explore the interior mountains. He then hired a pulled rickshaw that led him to Uruwa, Kumagaya and Takasaki. He climbed Mount Asama to observe Mount Fuji before returning to Komoro and reaching the Shimosuwa thermal station at Lake Suwa. He then crossed the provinces of Mino and Omi and joined Lake Biwa and via a small steam train reached Otsu.
He then visited Kyoto before traveling to Osaka and Kobe. After a three-month stay, he embarked on January 20 1883 for Hong Kong. He reached Victoria Harbour and Kowloon then fared up the Pearl River to Guangzhou.
He then stopped in Saigon, Singapore and Colombo and returned to Paris on March 6 1883.
In April-May 1894, he made a trip to the Mediterranean and returned with an album of sixty-four photographs of Greece and Turkey preserved today at the Bibliothèque nationale de France. [2]
