The histories of IUGG and its constituent Associations feature the significant contribution of Bureau officers to the conception and evolution of their respective scientific programmes since the birth of the Union in 1919.

The writings of Past Presidents, along with those of other officers, have long been important elements of the historical records. In the case of IAHS, the reading of the archives from the early years cannot help us to appreciate the coming of age of the hydrological sciences at that time.

The first President of IAHS (then know as the Section of Hydrology of IUGG) was E.B.H. Wade. In examining the archives of IAHS, we found it curious that Mr Wade had left no record of his activities during his tenure, which lasted from 1922 to 1933. In order to shed some light on this anomaly we resorted to the search of diverse archives available on the Internet. It was thus possible to establish a profile of Mr Wade and his activities during his career and of his involvement in the hydrological sciences.

Mr Wade was born in 1872 in Peking; his father was a British diplomat, his mother was the daughter of the renowned astronomer William Herchel. He attended Cambridge University and graduated with 1st Class Honours in Natural Science. He then joined the research group led by Prof. J.J. Thomson FRS, the discoverer of the electron. During the period 1901-1903 he published work on the development of measurement methods of physical and astronomical phenomena.

Mr Wade took up a position at the Egyptian Survey Department (Cairo) in 1904 and in the following year led the Egyptian-Turkish Boundary Commission. The report of the Commission in 1907 on the delimitation of the Turco-Egyptian boundary between the vilayet of the Hejaz and the peninsula of the Sinai has to this day far reaching consequences in the political context of the Middle East.

In 1909 Mr Wade published a paper with H.E. Hurst, the renowned hydrologist, who had started to work for the Survey Department in 1906. In 1919 Mr Wade joined the Physical Department of the Ministry of Public Works, headed by his colleague Hurst, to participate in the collection of rainfall and river flow in the Nile basin of Egypt, Sudan and East Africa. This data was required for future project on the control and conservation of Nile Waters.

As Director of Research Mr Wade supervised the improvement of methods for discharge measurement, particularly with regard to the development and calibration of current meters at low velocities and at higher discharges subjected to Turbulence. Field work was carried out in 1921 and 1922 and the results published in a series of paper by the Physical Department of the Ministry of Public Works during the period of 1921 and 1924.

At the end of April 1922, he attended the IUGG Meeting at Rome at which he became President of the Section of Hydrology for 6 years. In 1928 his mandate was renewed for a further 6 years, but was replaced in 1933 (Lisbon General Assembly) by Jan Smetana from the Czechoslovakian Republic.

Three years after the start of his first term as President Mr Wade retired from the Egyptian Civil Service at the age of 53. He lived in Geneva from 1925 until the commencement of WWII. We know little of Mr Wade during his retirement. As far as we know he left no records of his presidency with IAHS archives. In his obituary by J.H. Reynolds in 1946, one finds that he was an avid pianist and interested in musical composition. In later life he devoted himself to music entirely. He died in London in 1945.
