This date is too late by about a year.

According to the Antonín Dvořák reference site, the first ever public performance of a work by Dvořák was the song "Remembrance" (Vzpomínání) from Songs on Words by Eliška Krásnohorská, B23, performed in Prague on 10 December 1871. The site's chronology likewise lists 10 December 1871 as the "first known public performance of an independent work".

So 1872 was not the year of the first public performances of his works; public performance began in 1871.

This clause misdates the birth of Dvořák's first son by one year.

The Antonín Dvořák chronology records "4. 4. birth of son Otakar" under 1874. The biography page on Dvořák's marriage also states that Anna gave birth to their first-born son Otakar in April 1874.

So 1875 was not the year his first son was born.

The article says Dvořák re-entered the competition and did not win, but the primary chronology says otherwise.

The official Dvořák chronology lists:

• August 1875: "second application for a state scholarship"
• 5 March 1876: "is awarded his second state scholarship of 400 gulden"

The official biography page summarizes this even more clearly: Dvořák was "successful in subsequent years, winning the award five years in a row."

So the statement that he entered again and "did not win" is contradicted by the documented award of a second state scholarship in 1876 based on that next application cycle.

This sentence overstates the performance history of the Fourth Symphony.

The official Dvořák work page for Symphony No. 4 in D minor, Op. 13, B41 distinguishes between an early partial performance and the full premiere:

• 3rd movement: 25 May 1874, Prague
• complete symphony: 6 April 1892, Prague

The same page explains that although the symphony was completed in March 1874 and its third movement was heard in May 1874, "it was eighteen years before audiences would hear the complete work".

So it is wrong to say that both the Third and Fourth Symphonies had been premiered in Prague in spring 1874. That is true for the Third Symphony, but for the Fourth only one movement was played then; the full symphony had to wait until 1892.

The "three days" figure refers to the initial sketch, not to completion of the whole quartet.

The official Dvořák work page dates the String Quartet No. 12 in F major, Op. 96 "American" to 8 June – 23 June 1893. It further explains that "the entire sketch for the quartet emerged within ... 72 hours" but "the whole score was finished within twelve days."

So saying that Dvořák composed the quartet in three days is inaccurate. A more precise statement is that he sketched it in about three days and completed the full score later that month.

The official work catalogue for String Quintet No. 1 in A minor, Op. 1, B7 gives its date of composition as "6 June 1861 - ?". The same site notes that this was the work with which Dvořák, then aged 20, officially launched his career as a composer.

So the statement placing this composition in 1860 is incorrect; the documented composition date begins in 1861.

The performance date given here is incorrect.

The official Dvořák work page for Songs on Words by Eliška Krásnohorská, B23 lists the premiere of No. 5, Remembrance (Vzpomínání), as 10 December 1871, Prague. It also says this performance was "the first ever public performance of a work by Dvořák".

So the article's dating of that public performance to October 1871 is contradicted by the documented premiere date of 10 December 1871.
