What do the St. Stephen’s Formula Factory in Quarry and the FreePort of Csepel have in common? Designed for these two sites, István Menyhárd, one of the iconic figures of hungarian reinforced concrete shell construction, distorted quadrilateral shells in the 1930s. This was an outstanding achievement internationally, as the membrane theory of distorted quadrilaterals had been published only a few years earlier by French engineer Ferdinand Aimond. Apart from Menyhart, only Aimond and Giorgo Baroni built structures like this in Italy, about the same time. Research and documentation of French and Italian examples has recently been launched [1,2] – the early history of hyperbolic shells is now being recorded. Today, both Hungarian examples have been destroyed. The 120th anniversary of István Menyhárd’s birth in 2022 offers a suitable apropos to document the two early memories of hungarian shell construction in a dignified manner based on the remaining secondary sources (starting  point). Sisyphean data collection (literature research, archives, museums, digital archives), 3D reconstruction, can be expanded by structural control according to interest.
