Gerardus Mercator (1512 – 1594)
Gerardus Mercator, a Flemish cartographer and geographer, is best known for his creation of the Mercator projection, a cylindrical map projection that revolutionized the field of cartography and navigation. Born in Rupelmonde, Belgium, Mercator was a true renaissance man, with interests and expertise spanning a wide range of fields, including mathematics, astronomy, and geography.
Mercator’s most significant contribution to the field of geography was undoubtedly his creation of the Mercator projection. First introduced in 1569, the Mercator projection was designed to preserve the shape of landmasses while sacrificing accuracy in terms of size and distance. This made it particularly well-suited for navigation, as it allowed sailors to plot a straight-line course between two points on the map.
The Mercator projection quickly became the standard map projection for navigation and remained in use for centuries, with its influence still felt to this day. However, the projection has also been criticized for its distortion of size, particularly in the polar regions, which appear much larger than they actually are.
In addition to his work on the Mercator projection, Mercator also made significant contributions to the field of geography through his creation of globes and atlases. His “Atlas sive Cosmographicae Meditationes de Fabrica Mundi et Fabricati Figura” (Atlas or Cosmographical Meditations on the Fabric of the World and the Figure of the Fabrick’d), published in 1595, was one of the first modern atlases and helped to establish the format for future generations of cartographic works.
Mercator’s legacy lives on to this day, with his projection and atlases serving as a testament to his skill and innovation as a cartographer and geographer. His work has inspired countless cartographers and geographers and has helped to shape the way we view and represent the world around us.

Carl O. Sauer, an American geographer and professor, is widely regarded as one of the most influential figures in the history of modern geography. Born in Warrenton, Missouri, Sauer was a pioneer in the field of cultural geography, which seeks to understand the relationship between human culture and the natural environment.
Sauer’s most significant contribution to the field of geography was his work on the concept of “cultural landscapes.” In contrast to the environmental deterministic views of earlier geographers, who emphasized the importance of the natural environment in shaping human activity and culture, Sauer argued that human societies play a critical role in shaping and transforming the natural environment. His work, which drew on the theories of German geographer Otto Schlüter, helped to establish cultural geography as a distinct area of study and laid the foundation for future generations of geographers and anthropologists.
In addition to his work on cultural landscapes, Sauer also made significant contributions to the field of historical geography through his studies of the pre-Columbian Americas. His “The Early Spanish Main” (1966) was a groundbreaking work that helped to shed light on the complex and dynamic history of the Caribbean region and laid the foundation for future generations of historical geographers.
Sauer’s legacy lives on to this day, with his emphasis on the importance of human culture in shaping and transforming the natural environment continuing to inspire and inform the work of geographers and anthropologists around the world. His work has helped to shape our understanding of the complex and dynamic relationship between human societies and the natural world, and has laid the foundation for the modern field of cultural geography.
Doreen Massey (1944 – 2016)
Doreen Massey, a British geographer and social scientist, is widely regarded as one of the most influential figures in the history of modern geography. Born in Manchester, England, Massey was a pioneer in the field of feminist geography, which seeks to understand the ways in which gender relations shape and are shaped by geographic processes and spaces.
Massey’s most significant contribution to the field of geography was her work on the concept of “power-geometry.” In her view, space and place are not neutral or static entities, but rather are constantly being produced and reproduced through the unequal power relations that exist between different social groups. Her work, which drew on the theories of French philosopher Michel Foucault, helped to establish feminist geography as a distinct area of study and laid the foundation for future generations of geographers and social scientists.
In addition to her work on power-geometry, Massey also made significant contributions to the field of economic geography through her studies of the spatial dimensions of economic inequality and globalization. Her “Spatial Divisions of Labour” (1984) was a groundbreaking work that helped to shed light on the ways in which the global economy is structured and organized across geographic space.
Massey’s legacy lives on to this day, with her emphasis on the importance of power relations and social justice in shaping geographic processes and spaces continuing to inspire and inform the work of geographers and social scientists around the world. Her work has helped to shape our understanding of the complex and dynamic relationship between space, place, and social inequality, and has laid the foundation for the modern field of feminist geography.
David Harvey (1935 – present)
David Harvey, a British-American geographer and social theorist, is widely regarded as one of the most influential figures in the history of modern geography. Born in Gillingham, England, Harvey is a pioneer in the field of Marxist geography, which seeks to understand the ways in which capitalist social relations shape and are shaped by geographic processes and spaces.
Harvey’s most significant contribution to the field of geography has been his work on the concept of “uneven geographical development.” In his view, the capitalist mode of production necessarily produces spatial inequalities, as capital seeks to maximize profits by moving to areas with lower costs of production and higher rates of exploitation. His work, which draws on the theories of Karl Marx and other critical social theorists, has helped to establish Marxist geography as a distinct area of study and has laid the foundation for future generations of geographers and social scientists.
In addition to his work on uneven geographical development, Harvey has also made significant contributions to the fields of urban studies and social theory through his analyses of the role of cities in the global economy and the ways in which social movements and political struggles are shaped by and shape urban spaces. His “Social Justice and the City” (1973) and “The Condition of Postmodernity” (1989) are considered classic works in the field of critical urban studies.
Harvey’s legacy continues to shape the discipline of geography and beyond, with his emphasis on the importance of understanding the ways in which capitalist social relations shape and are shaped by geographic processes and spaces continuing to inspire and inform the work of geographers, social scientists, and activists around the world. His work has helped to deepen our understanding of the complex and dynamic relationship between space, place, and social inequality, and has provided critical tools for imagining and fighting for a more just and equitable world.
