International Hydrographic Organization
The IHO was established in 1921 as the International Hydrographic Bureau (IHB). The present name was adopted in 1970 as part of a new international Convention on the IHO adopted by the then member nations. The former name International Hydrographic Bureau was retained to describe the IHO secretariat until 8 November 2016, when a revision to the Convention on the IHO entered into force. Thereafter the IHB became known as the "IHO Secretariat", comprising an elected Secretary-General and two supporting Directors, together with a small staff of 17, at the Organization's headquarters in Monaco.
International Hydrographic Organization
During the 19th century, many maritime nations established hydrographic offices to provide means for improving the navigation of naval and merchant vessels by providing nautical publications, nautical charts, and other navigational services. There were substantial differences in hydrographic procedures charts, and publications. In 1889, an International Maritime Conference was held at Washington, D.C., and it was proposed to establish a "permanent international commission." Similar proposals were made at the sessions of the International Congress of Navigation held at Saint Petersburg in 1908 and the International Maritime Conference held at Saint Petersburg in 1912.
