Ghatak is an Indian family name and surname found amongst Bengali Hindu Brahmins.
Ghataks (literally, one who makes things happen) or matchmakers were middleman who established links between the two parties in a marriage. In the past it was not the custom of Indian society, especially of Bengali society, to allow boys and girls to mix freely. This is why the services of Ghataks were widely used to arrange marriages. Many Ghataks were professionals, and matchmaking was their source of livelihood. When the matchmaking resulted in a wedding, Ghataks used to be rewarded by both parties.
In the past, educated and respectable people used to take up matchmaking as a profession. They were known as 'Kulacharya' and used to maintain books with detailed histories of families. Some of these books have been used as sources for writing the history of Bengal. Some of the well-known matchmakers were Edu Mishra, Hari Mishra (c 13th century), Dhruvananda Mishra, Debibar Ghatak (15th century) and Nulo Panchanan (18th century). They used to enjoy a great deal of social prestige.
