SS Frankfurt

At roughly 12:15 AM (Titanic' time) on 15 April 1912, while eastbound from Galveston to Bremerhaven,^[3] Frankfurt was the first vessel to respond to distress signals from the RMS Titanic.^[4] Under the orders of Captain Edward John Smith, Titanic's wireless operator, Jack Phillips, tried to reach out to Frankfurt to acknowledge his position.^[7] However, Frankfurt's operator, W. Zippel, only answered with "Standby".^[8] It can only be speculated whether he informed his captain at this time. At 12:38 Frankfurt sent her position to Titanic and was told by Phillips to inform his bridge and come to assistance. At this time the Frankfurt was between 120 and 150 nautical miles away from the Titanic.^{[3][8][9][10]} This already made it difficult for Frankfurt's wireless operator to hear and understand Titanic's calls. According to some reports the Frankfurt's wireless signal strength indicate that she was actually closer to the Titanic (According to the wireless operator on Mount Temple and the surviving wireless operator on Titanic, Harold Bride). However, this is most likely due to a more powerful wireless transmitter installed in the Frankfurt compared to the surrounding ships.

At around 1:23 AM, Titanic's wireless transmitter lost power, hence debilitating her communication with Frankfurt and many other ships responding to her distress calls. As Frankfurt was no longer receiving calls from Titanic, Zippel tried to regain contact with her with the message "What is the matter with you?", which had unintentionally angered Phillips.^[11] Phillips, frustrated that the Frankfurt had seemed not to have known the situation the whole time after receiving Titanic's first distress call, answered: "You are a fool! Stand by and keep out!". However, this was most likely not heard by Frankfurt's operator due to the distance between the ships and Titanic's fading signal strength.

George Behe of the Titanic Historical Society pointed out that Zippel, at the time of Phillips' outrage, was well aware of the seriousness of Titanic's situation. Even though Hattorff did not know the actual scope of the situation, he assumed it to be the worst with the limited details he had. He even assumed that the Titanic went down at 1:23 AM since that was the last time that he heard a message from Titanic.^[9]

Once the Titanic's situation was realized, according to Überall (a German magazine), the Frankfurt's captain, Hattorff, steered toward the Titanic's position at full speed. He ordered the ship's galley to bake bread and the crew to provide blankets for the passengers they would rescue. Captain Hattorff estimated that by the given coordinates, he could make it to the site by 11:00 AM.^[9]

The Frankfurt was the first to notify the SS Californian, the closest ship to the Titanic, that she had sunk overnight.^[12]

Frankfurt Seamount, one of the Fogo Seamounts southeast of the Grand Banks of Newfoundland in the North Atlantic Ocean, is named after Frankfurt.^[13]
