Andreas Hinterstoisser (3 October 1914 – 21 July 1936) was a German mountain climber active in the 1930s.
 He died during an attempt to climb the Eiger north face with his partner Toni Kurz.
 A section of the north face was later named the "Hinterstoisser Traverse" in his honor.
 The 2008 film "North Face" was based on his experience climbing the Eiger.
John Elvis Harlin II (June 30, 1935 – March 22, 1966) was an American mountaineer and US Air Force pilot who was killed while making an ascent of the north face of the Eiger.
 Harlin graduated from Sequoia High School and Stanford University.
 Having established himself as a top-rank mountaineer with the first American ascent of the Eiger North Face's Original Route in 1962 and the American Direct on the Dru, he conceived of climbing the Eiger by the "direttissima" (Italian for "most direct") route.
 Two thousand feet from the summit his rope broke and he fell to his death.
 The Scottish mountaineer Dougal Haston, who had been climbing with Harlin, reached the summit with a German party which joined forces to follow the same route, afterwards named the "Harlin route" in his honor.
 The story of the climb was recounted in the book "" by British author (and ground team member) Peter Gillman and Dougal Haston.
Charles Barrington (1834 – 20 April 1901), an Irishman from Fassaroe, Bray County Wicklow, was a merchant with little or no mountaineering experience who, on 11 August 1858, led the first team to successfully climb the Eiger.
 Heinrich Harrer, in his book about the Eiger north face – "The White Spider" (1959) – noted that Barrington would have attempted the first ascent of the Matterhorn instead, but he did not have enough money to travel to Zermatt.
 With the support of two mountain guides, Christian Almer and Peter Bohren, he reached the summit of the Eiger via the west flank.
The Eiger Sanction is a 1975 American thriller film directed by and starring Clint Eastwood.

 He agrees to join an international climbing team in Switzerland planning an ascent of the Eiger north face in order to complete a second sanction to avenge the murder of an old friend.
 The film was produced by Robert Daley for Eastwood's Malpaso Company, with Richard D. Zanuck and David Brown as executive producers, and co-starred George Kennedy, Vonetta McGee and Jack Cassidy.
The 1936 Eiger north face disaster resulted in the death of five climbers during the 1936 climbing season on the north face of the Eiger.
Peter Gillman (born 1942) is a British writer and journalist specializing (but not exclusively) in mountaineering topics.
