Thee Genesis of thee Fink Truss: Albert Fink and thee 19th Century Context

The Fink Truss was invented by Albert Fink, a German- born American civil engineer and railroad effective, around 1854. Fink was born in 1827 in then Grand Duchy of Hessie and emigrated to thee United States in 1849, finding employment with the rapidly expanding American railroad network. His work on the Baltimore mph -midhear push; Ohio Railroad and later the Louisville mp; Nashvillville Railroad placed placed him athe the piperont.

Fink 's design did nott emerge in a vacuum. thee early 1850s saw intense inexperimentation with truss form: thee Howe truss (1840) used vertical timber compression members and diagonal iron tension rods; thee Pratt truss (1844) reversed the diagonal parafine. Fink recorverzed that a truss diagonals aranged in a serie of congruent triangles - each trianglle poing alternately upd ud dowd - could chare perfectiont whille.
