In connection with the complete re-construction of the old Heerstraße from Hanover to Hildesheim, the Hildesheimer Straße from the Catholic cemetery to the Döhrener Tower at the end of the 18th century by the military cartographer Georg Sigismund Otto Lasius , one can be found in the road file to this day by the "well-known Ing.-Leutnant Seveloh “made plan of the St. Aegidii field for the purpose of laying out the planned new road from 1792 .

In military terms, Seweloh first appeared in 1793, when he was an ensign in the Hanoverian artillery regiment and was appointed second lieutenant on September 5, 1794 .

Seweloh's son Louis Friedrich Otto Heinrich Rudolph Seweloh was born on September 12, 1816 . In the same year Seweloh was appointed head of the Royal Hanoverian Engineering Corps. The colonel - like his son later - dealt in particular with the procedures of common division and the regulation of the municipal boundaries in the kingdom.

In the years 1825 to 1836 Seweloh made various maps on a scale of 1.2500 over the area of ​​the then Steintor garden community and the Aegidientor garden community , which had merged administratively to form the suburb of Hanover , which was previously formed from 14 localities . Seveloh's maps later, together with plans by August Wilhelm Papen and the maps of the riding forester Johann Philipp Wilhelm Köhler, formed the basis for the “Official Road Map” of 1854, which was probably compiled by the draftsman and later chief draftsman Friedrich Sohnrey .

Until 1824 Seweloh was listed as Friedrich Seweloh in the Hanoverian and Electoral-Braunschweig-Lüneburg state calendar .

In the period from 1835 to 1837, Karl Seveloh also surveyed the entire municipal property, including the municipal church and foundation plots, on behalf of the City of Hanover. He transferred his measurements to three large maps covered with squares on a scale of 1.2500. These later served in turn in part as the basis for the production of cadastral maps for the areas of Große Bult and Kleine Bult and were already considered exemplary in comparison with other linking maps of their time.

Seweloh was considered a passionate military man and among other things collected around 500 war cards about the campaigns of Duke Ferdinand of Braunschweig .

From the correspondence with Carl Friedrich Gauß , a letter from Seweloh dated June 2, 1841 has been preserved in Gauß's estate.

While the Hannoversche address book for the year 1826 recorded the residence of the lieutenant colonel "on the Posthofe except the Steinthor ", the address book for 1848 listed the colonel a. D. Karl Seweloh at 1. Auestrasse 105a , while in the same year the captain was registered with the artillery and teacher at the Military Academy (Karl) Theodor Seweloh at Neuestrasse 24 .
