Joseph Haydn's Symphony No. 1 in D major, Hoboken I/1, was written in 1759 in Dolní Lukavice, while in the service of Count Morzin. Though identified by Haydn as his first symphony, scholars are not sure if it is actually the first he composed, or even the first that survived to posterity. While it is reliably known that No. 1 was written in 1759, H. C. Robbins Landon cannot rule out that No. 2, No. 4, or both could have been composed in 1757 or 1758.

To remain perplexed about this small but interesting point would be to ignore no less than the composer himself."
