This is because the pronunciation of "Euler" begins with a vowel sound ("oi"), so "an" is preferred. Besides, Wikipedia and most other articles uses "an" too, so using "an" will be better for consistency. However, I don't think it really matters, as long as your readers can understand. Map of Königsberg in Euler's time showing the actual layout of the seven bridges, highlighting the river Pregel and the bridges.
