Henenu (high steward)

Hannu, Hennu or Henenu was an Egyptian noble, serving as "m-r-pr" "majordomo" to Mentuhotep III in the 20th century BC. He reportedly re-opened the trade routes to Punt and Libya for the Middle Kingdom of Egypt. He was buried in a tomb in Deir el-Bahri, in Theban Necropolis, which has been catalogued as TT313.
He is known from two inscriptions, in Wadi Hammamat no. 114 (ca. 2000 BC) as "hnw" and in his Deir el-Bahari tomb as "hnnw". It is unclear whether the two inscriptions refer to the same person. William C. Hayes postulated their identity while Herbert Eustis Winlock was hesitant to identify them. 
James P. Allen considers "hnw" a successor of "hnnw" as the pharaoh's "m-r-pr".
Travels.
In the eighth year of the reign of Mentuhotep III, Hannu set out from Coptos at the head of a three-thousand-man strong army, crossed the mountainous Eastern Desert by way of Wadi Hammamat, and went on to the coast of the Red Sea.
Inscriptions.
Hannu wrote of his expedition in stone. Under Sankhare (Mentuhotep III), whose name occurs as the 58th on the Table of Abydus, lived a functionary named Hannu, who records on a rock-inscription, in this same valley of Hammamat, some particulars of his reign, from which it appears that the kings of this dynasty had dealings with Arabia; and the trade thus introduced directly by the valley route from Coptos to the Red Sea, seems to have revived the fallen fortunes of the old monarchy.
The first voyage to the land of Punt took place under Sankh-ka-ra. According to the words of the rock inscription, everything needful was wisely prepared for the expedition, for which Pharaoh chose as leader and guide the noble Hannu, who gives us the following account of his voyage:
I was sent to conduct ships to the land of Punt, to fetch for Pharaoh sweet-smelling spices, which the princes of the red land collect out of fear and dread, such as he inspires in all nations. And I started from the city of Coptos.—And his Holiness gave the command that the armed men, who were to accompany me, should be from the south-country of the Thebai'd.'
After a destroyed passage of the inscription, of considerable length, of which, however, enough has been preserved to show us that the narration went on to state that the armed force was sent with the expedition to protect and defend it against the enemy, and that officers of the king, as well as stonecutters and other workpeople, accompanied it, Hannu continues:
Then I reached the Great Green (w"ȝ"ḏ-wr). Then I made the ships and I dispatched them with all manner of things and made for them a great oblation of cattle, oxen and gazelles. When I returned from the Great Green, I performed what His Majesty commanded: I brought for him every product that I found on the shores of God's Land. I descended by WSg (unidentified) (and) Ro-Henu (Wadi Hammamat). I brought for him splendid blocks of stone for the temple statues.
Principal stations.
In his account of the journey Hannu speaks of five principal stations at which the wanderer halted, and man and beast (then probably the ass, the only beast of burden proved to have been used in those times) strengthened themselves for their further progress by enjoying the fresh drinking water. This is also the same road that, in the time of the Ptolemies and Romans, led from Coptos in an easterly direction to the harbour of Leucos Limen (now Qossier) on the Red Sea; the great highway and commercial thoroughfare of merchants of all countries, who traded in the wonderful products of Arabia and India; the bridge of the nations, which of old united Asia and Europe.
