The opus 2 sonatas were published in at least 3 editions in the 1790s by the Corri-Dussek company in London as by Madame Dussek, and there is no reason to doubt that the 6 sonatas of opus 2, including the famous C minor sonata published and misattributed by Schott as by JL, are anything but the work of Sophia. Paris editions of opus 2 published by Pleyel only bear the name Dussek, leading Zabaleta to his misattribution, but nobody actually claimed opus 2 as the work of JL rather than Dussek before the mid-20th century.[citation needed]
