Hartwich was born into a family of clergymen. He was a great-nephew of Martin Heinrich Klaproth on his mother's side . He attended the Brandenburg High School and the Berlin Building Academy . After additional private tuition in mathematics, he first passed the surveyor's examination in 1819 . In 1823 he passed the conductor examination (construction manager examination, first state examination), in 1827 the master builder examination ( second state examination ).

He worked within the state building administration initially in hydraulic engineering . In 1824 he was entrusted with the regulation work of the Finow Canal and the Havel near Liebenwalde, in 1827 with the construction required to continue the Finow Canal, in 1829 as a hydraulic engineering inspector in Steinau (Silesia, today Ścinawa ) and in 1834 as a government and building councilor in Danzig . There he completed the jetties in Danzig- Neufahrwasser , carried out the work connected with the breakthrough of the Vistula into the sea near Neufähr and led the construction of the episcopal castle and the restoration of the church in Pelplin .

From the end of the 1830s he turned to the emerging railway construction, in 1845 - on leave from civil service - he took over the construction of the Stargard-Poznan Railway, the most demanding structure of which was the arched bridge over the Warta near Wronke . In 1849 he was a lecturer Council appointed to the royal Prussian Ministry of Commerce and a member of the Oberbaudeputation appointed where it except the railways amelioration of low or breakage was transmitted. From 1849–1855 he was also a member of the board of directors of the Berlin Building Academy, and from 1850–1856 he was a member of the editorial board of the Bauwesen magazine . In 1855 he served as the 5th class president for rail and land transport for the World Exhibition in Paris and toured France.

In 1856 Hartwich resigned from the civil service and took over the management of the construction department of the private Rheinische Eisenbahn-Gesellschaft in Cologne, whose main structures he published in three parts under the title Extension Buildings of the Rheinische Eisenbahn-Gesellschaft (cf. publications ). Unlike in the state building administration, he was able to implement his own developments and findings here, B. the introduction of the so-called “Hartwich rail” or “central turnout and signaling apparatus” based on the British model. Of the bridge constructions carried out under his direction, the Pfaffendorfer Bridge in particular was recognized for its “boldness of construction” and “beauty of form”. A further development of this type of construction was the Duisburg-Hochfelder railway bridge built by Gutehoffnungshütte around ten years later after it was planned .

1871 Hartwich was in the after Empire resulting Reich Chancellery called, but took over in 1872 the management of the German railway company , but from which he retired again before its collapse. In the last five years of his life he was only active as an author. In his publication, Comments on the Course of the Development of the Railway System (Berlin 1877), he advocated the promotion of the local railways . In addition, Hartwich was an early and staunch supporter of the construction of the Berlin Stadtbahn , which was far from being completed when he died on March 17, 1879.
