Luigi Porro Lambertenghi

Count Luigi Renato Porro-Lambertenghi (July 12, 1780 in Como – February 9, 1860 in Milan) was an Italian nationalist, businessman, and politician.

He was forced to leave Italy in March 1821, while in Milan, as the Austrian police were rounding up everyone suspected of conspiring against the government.

His escape was effected by Timothy Yeats Brown, who drove out of Milan with Lambertenghi disguised as his footman.

He fled to Geneva, and made his way to England in early 1822 via Paris, where Yeats Brown vouched for him at the Alien Office.

[5] Lambertenghi's grandson, Count Giulio Porro-Lambertenghi, was among the dignitaries who attended the Canonization of Joan of Arc.
