Parchevich Ridge (Parchevich Rid \'par-che-vich 'rid\) is a partly ice-free ridge of elevation 370 m situated in Breznik Heights north of Hardy Cove, 690 m south of Benkovski Nunatak, and 1.7 km southwest of Santa Cruz Point on Greenwich Island, Antarctica.
 Surmounting Hardy Cove to the southwest and Gruev Cove to the east-northeast.
 Bulgarian topographic survey Tangra 2004/05.
 Named after Petar Parchevich (1612–74), a Bulgarian Catholic bishop and diplomat who campaigned for Bulgarian independence in 1630–45.
Hvoyna Cove (Bulgarian: "залив Хвойна" , ‘Zaliv Hvoyna’ \'za-liv 'hvoy-na\) is the 1.7 km wide cove indenting for 1 km Davis Coast in Graham Land, Antarctica.
 It is part of Jordanoff Bay entered east of Wennersgaard Point and west of Kamenar Point.
 The cove is named after the settlement of Hvoyna in Southern Bulgaria.
Haskovo Cove (Zaliv Haskovo \'za-liv 'ha-sko-vo\) is a 2.1 km wide cove indenting for 1 km the northern coast of Greenwich Island between Aprilov Point and Miletich Point in the South Shetland Islands, Antarctica.
 Situated next east of Crutch Peaks, southwest of Ongley Island and northwest of Sevtopolis Peak.
 Shape enhanced as a result of Teteven Glacier’s retreat in the late 20th and early 21st century.
 The cove is named after the city of Haskovo in Southeastern Bulgaria.
Salmon Cove ( ) is a cove 4 nmi southeast of McCall Point on the east side of Lallemand Fjord in Graham Land.
 It was mapped by the Falklands Islands Dependencies Survey from surveys and air photos, 1956-59.
 It was named by the UK Antarctic Place-names Committee for Eric M.P. Salmon, an assistant Falklands Islands Dependencies Survey meteorologist who spent several seasons in Antarctica between 1950-56, and visited this cove in 1956.
Irving Langmuir (January 31, 1881 – August 16, 1957) was an American chemist and physicist.
 His most noted publication was the famous 1919 article "The Arrangement of Electrons in Atoms and Molecules" in which, building on Gilbert N. Lewis's cubical atom theory and Walther Kossel's chemical bonding theory, he outlined his "concentric theory of atomic structure".
 Langmuir became embroiled in a priority dispute with Lewis over this work; Langmuir's presentation skills were largely responsible for the popularization of the theory, although the credit for the theory itself belongs mostly to Lewis.
 While at General Electric from 1909 to 1950, Langmuir advanced several basic fields of physics and chemistry, invented the gas-filled incandescent lamp and the hydrogen welding technique, and was awarded the 1932 Nobel Prize in Chemistry for his work in surface chemistry.
 The Langmuir Laboratory for Atmospheric Research near Socorro, New Mexico, was named in his honor, as was the American Chemical Society journal for surface science called "Langmuir".
Chinstrap Cove is a cove 6 km north-east of Escarpada Point on the north-west coast of Clarence Island, South Shetland Islands, Antarctica entered northeast of Vaglen Point.
 The cove has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a large breeding colony of about 20,000 pairs of chinstrap penguins, after which it was named by the UK Joint Services Expedition which visited the site in 1970-1971.
 The 74 ha IBA includes the ice-free area south of the cove, extending 2 km along the coast.
Harmony Cove ( ) is a cove entered between Harmony Point and The Toe on the west side of Nelson Island, in the South Shetland Islands, Antarctica.
 It was named by American sealers in about 1820 after the sealing vessel "Harmony", under Captain Thomas Ray, one of several American sealing vessels headquartered at Harmony Cove during the 1820–21 season.
Coppermine Peninsula is the 1.7 km long, 500 m wide and rising to 105 m rugged rocky promontory forming the northwest extremity of Alfatar Peninsula and Robert Island in the South Shetland Islands, Antarctica and lying between English Strait to the west and Carlota Cove to the east.
 It is linked to Alfatar Peninsula to the southeast by a narrow isthmus bounded by Carlota Cove to the north and the 1 km wide and 460 m indenting "Coppermine Cove" ( ) to the south.
 The feature is named in association with the adjacent Coppermine Cove, a descriptive name given by sealers in about 1821 from the copper-coloured staining of the lavas and tuffs in the area.
Vinitsa Cove (Bulgarian: "залив Виница" , ‘Zaliv Vinitsa’ \'za-liv 'vi-ni-tsa\) is the 3.75 km wide cove indenting for 1.9 km Davis Coast in Graham Land, Antarctica east of Cape Page and west of Havilland Point.
 The cove is named after the settlement of Vinitsa in Southern Bulgaria.
Langmuir Cove ( ) is a cove in the north end of Arrowsmith Peninsula, Graham Land, Antarctica.
 It was named by the UK Antarctic Place-Names Committee for Irving Langmuir, an American physicist who studied the formation of snow.

Question: What is the person whom a cove in Antarctica cove is named for?
Answer: famous 1919 article "The Arrangement of Electrons in Atoms and Molecules
