Reginald Claypoole Vanderbilt (January 14, 1880 – September 4, 1925) was a member of the Vanderbilt family. He was the father of Gloria Vanderbilt and maternal grandfather of Anderson Cooper. An avid equestrian, Vanderbilt was the founder and president of many equestrian organizations. He gambled away most of his inheritance.

Early life

Reginald Claypoole Vanderbilt was born on January 14, 1880, in Manhattan, New York. He was the youngest son of Cornelius Vanderbilt II (1843–1899) and Alice Claypoole Gwynne (1845–1934). Among his siblings was Gertrude Vanderbilt (1875–1942), who married Harry Payne Whitney, Alfred Gwynne Vanderbilt (1877–1915), and Gladys Moore Vanderbilt (1886–1965), who married Count László Széchenyi.

Reginald was a grandson of William Henry Vanderbilt (1821–1885), and great-grandson of Commodore Cornelius Vanderbilt (1794–1877).

Editorial analysis

Why this record matters

“Reginald Claypoole Vanderbilt” is worth following because a concise public description often conceals a longer documentary argument. Here, Reginald, Claypoole and Vanderbilt provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 11, 2026. The linked authority identifier is Q2010288. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1880, 1925, 1843 and 1899.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
