Early life

Roberto Ivens was the son of Margarida Júlia de Medeiros Castelo Branco and Robert Breakspeare Ivens (1822-?). Margarida was of lower nobility and Roberto's Grandfather, William Ivens, was a merchant awarded the Ivens

George III in 1816.[1] Robert Breakspeare Ivens was a great-grandson of Thomas Hickling (Boston 1745-1836 Ponta Delgada) the American vice-consul in Ponta Delgada

Travels

Ivens began his travels in

Angola in 1872. On 10 October 1874 he completed three years of travels in the colonies. Returning to Portugal in January 1875, Ivens made examination for lieutenant. In April 1875, he sailed on the Duque de Terceira for Portuguese São Tomé and Príncipe
and various ports of South America.

In 1876, Ivens set out for the United States, bringing Portuguese products to Philadelphia for the Centennial Exposition. His ancestor, Thomas Hickling, had been an ardent American revolutionary, and had in fact left Boston for the Azores following an argument with his loyalist father.[2]

Ivens went on an expedition into the provinces of

Mozambique beginning on 11 May 1877, and studied relations between hydrographic basins in Zambezi. His hydrographic studies are considered even today to be "amazingly perfect".[1] In the same year he was promoted to the rank of first lieutenant
.

Ivens went on an expedition on 21 June 1885 at

Berlin Conference, to travel between Angola and Mozambique, which ended in over 4,500 miles (about 8,300 km) of which 1/3 was uncharted in what was called "Pink Map
".

For his service to Portugal, Roberto had the honor of being named

Military Order of Aviz and was nominated on October 17 as secretary of the Commission of Cartography.[citation needed
]

Honours

Portugal has ten streets named after Roberto Ivens including one in Ponta Delgada named Avenida Roberto Ivens. Several schools are named in his honor, including Escola Básica Integrada Roberto Ivens, near his birthplace.

A species of African lizard, Lubuya ivensii, is named in his honor.[3]

He was also portrayed in the 500 Angolan escudo banknote issued in 1956.[4]

In 2019, TAP Air Portugal named an Airbus A321, registered CS-TXD, for Roberto Ivens.[5]
