Who completed Mozart’s Requiem after his death?

Wolfgang Amadeus Mozart’s Requiem in D Minor was left incomplete at the time of his death in 1791. The work was most famously completed by his student, Franz Xaver Süssmayr, whose handwriting in the manuscript confirms he finished several passages.123

While Süssmayr’s version remained the standard for many years, the extent to which he relied on Mozart’s original sketches and drafts remains a subject of historical debate. In more recent times, other musicologists have offered alternative completions, most notably [Robert D. Levin].312
