Mailov brothers

The Mailyan brothers (also spelled Mailoff) (Armenian: Մայիլյան եղբայրներ), were oil magnates, businessmen, and philanthropists of Armenian descent. Some sources consider them to be the first producers of caviar in Russia. They were also known for sponsoring numerous cultural projects in the city Baku such as the Mailov Theatre (now known as the Azerbaijan State Academic Opera and Ballet Theater). The Mailov brothers also sponsored many investment projects in Armenia as well.

The Mailyan brothers consisted of three brothers; Daniel, Ivan (Hovhannes), and Lazarus (Yeghia). The brothers were industrial capitalists who amassed a major fortune from oil. They were also successful in the caviar trade becoming the first company that produced caviar in Russia. Due to their success in the caviar industry, the family was known as the "Kings of fish roe".

After the Russian Revolution however, the Mailyan family sought refuge in France.

According to legend, a famous opera-soprano singer (which according to sources is either Antonina Nezhdanova or a certain Italian opera singer) visited Baku and had many performances in various casinos and residences in the city. However, when asked if she would return to Baku, she refused because she found that there was no decent opera house in the city. Daniel Mailov, who admired the personality and voice of the opera singer, commissioned an opera house to be built under the condition that she return to Baku.

The theatre was commissioned by the Mailyan brothers and was built by ethnic Armenian architect Nikolai Bayev. The project was also funded by the Azeri oil baron Zeynalabdin Taghiyev who challenged the Mailyan brothers in completing the project in a year. If the opera house was completed under a year, the costs of construction would be paid by him. The opera house was built in 10 months and Taghiev paid for the promised expense.
