Two reports of the symposium were elaborated: one for the Newsletter of the International Bernard Bolzano Gesellschaft, which can be found here, and one for the Proceedings of the 16th CLMPST, to be published by College Publications. In addition, two posters (posterA and posterB) were produced using a detail from a famous oil painting by Heinrich Hollpein and a lithograph based on it. The photographs by Dagmar Landová in Bildnisse Bolzanos are the sources.
Steve Russ was able to make a short research visit in December 2018 to an archive in Prague thanks to a grant from the British Society for the History of Mathematics, which led to the Bolzano Symposium at the 16th CLMPST. A report about this visit can be found here.
Mathematics and its Philosophy between the 18th and the 19th Century (2018)
Organised by Arianna Betti and Anna Bellomo, this workshop was held at the University of Amsterdam on the 13th-14th of July 2018. The aim was to foster discussion on the development of mathematics and related themes in philosophy in the German speaking context during the 18th and the 19th century.

Bolzano in Prague 2017
The meeting Bolzano in Prague 2017 was held from the 27th to the 29th of November. Organised by Steve Russ and Davide Crippa, this was a small research-oriented meeting celebrating the 200th anniversary of some major achievements of Bolzano to be found in his two mathematical works of 1817. The discussions focused mainly on the recently defended PhD theses of Johan Blok and Elías Fuentes Guillén, although other works were also discussed. Each session discussion was introduced and chaired by one of the participants.MORE

Final discussion and preparation of some output Report on the meeting.
The Google group “Bolzano in Prague 2017”, which still persists, was created to discuss matters that arose from the texts. If you would like to join the group, please send an email to Steve Russ (email@example.com). Research questions for discussion (from Steve Russ) can be found here.
A short paper by Steve Russ on the 200th anniversary of some mathematical achievements of Bernard Bolzano, entitled “Bolzano in Bohemia”, was published in Mathematics Today (Vol. 53, No. 6, pp. 278-281). Copies for personal use can be obtained on request to the author.
