Reading and comparing data from Arduino UNOUno EEPROM

I'm trying to read compare data from EEPROM  ( ArduinoArduino UNO  ). Reading Reading is working fine but comparing it using athe '==' operator is not working as expected.

//string 'True' is already stored in EEPROM

int addr = 0;
char value = EEPROM.read(addr);

Serial.println(value);// this line successfully prints the letter 'T'

// but this function is not working
if ( value == "T") {
  Serial.println("foo");
}
